In contrast muscle relaxant anxiety buy cheap nimotop 30mg on-line, married people were significantly more likely to report a decrease in sexual interest and activity (p = 0 muscle relaxant juice cheap nimotop. In terms of the impact of symptoms on daily life muscle relaxant equipment buy nimotop without a prescription, single and married people were likely to experience a similar level of impact of symptoms on their daily activities muscle relaxant erectile dysfunction purchase generic nimotop canada. The proportion of symptoms of right abdominal pain spasms down left leg order nimotop 30 mg with mastercard, depression back spasms 34 weeks pregnant 30mg nimotop sale, changing personality, difficulty managing time and jaundice was significantly higher among the unemployed than the employed (p 0. In terms of the impact of symptom on daily life, the prevalence of the impact of joint pain, right abdominal pain, decreased appetite and depression on daily and social activities was higher among the unemployed than the employed (p 0. Table 7-7: the proportion of symptom severity and hindrance of symptom among employed and unemployed Symptom severity Employment status Chi-square p value phi 2 Employed Unemployed (X) coefficient N=68 N=333 n (%) n (%) Itch 30(44. In other words, it seems that the perceived severity of symptoms increases with the progressive stage of cirrhosis. Besides that, the mean score of perceived symptoms severity extensively increased with the increasing number of complications and comorbidity (p 0. This means that there was a significant positive correlation between the number of both comorbidities as well as liver disease complications and severity of symptoms. Table 7-8 shows that severity of symptoms also had a significant positive association with the number of admissions to hospital because of liver disease. For example, whereas the mean score of symptoms severity for those never admitted to hospital was 30. On the other hand, the severity of symptoms did not have a significant association with the causes of cirrhosis. Furthermore, the mean score of the impact of the symptoms on daily activities significantly increased with the advanced stage of cirrhosis, comorbidities, complications and hospitalizations (p < 0. The disease stage has a relationship with the type of symptoms experienced similar to those found in prior studies. Therefore, it was important to run further statistical analyses (chi-square test) to compare the two groups of disease stages (compensated and decompensated cirrhosis). For instance, patients with decompensated cirrhosis were more likely than patients with compensated cirrhosis to have sexual problems (decrease in desire and activity) and difficulty in managing time (P 0. Moreover, in terms of the symptom hindrance, the impact of right abdominal pain, sleepiness during the day and decreased appetite on daily and social activities was higher among patients with decompensated cirrhosis than in patients with compensated cirrhosis (p 0. Table 7-9: the proportion of symptom severity and hindrance of symptom among compensated and decompensated patients Symptom severity Disease stage (n) Chi-square p value phi 2 Compensated Decompensated (X) coefficient N=201 N=200 n (%) n (%) Itch 101(50. This result suggests that with a perceived high social support there is a low perception of symptoms severity or vice versa. These results agree with the theory of unpleasant symptoms, which indicates that with insufficient social support there is a potential increase in the severity of symptoms (Lenz et al. It was found that the severity of symptoms was negatively associated with the perceived availability of social support, particularly support from spouse and family (r = 0. There was a significant negative association between perceived symptoms severity and general health perception. This suggests that the increase of symptoms severity and hindrance of daily activities due to symptoms worsens the perceived general health and vice versa (r=-0. Related to the factors associated with symptoms severity (Table 7-11 Model 1) the results show that the model significantly explained 19. Six variables significantly associated with symptoms severity [spouse support (b = -0. Low perceived spouse support, being married, females, increasing number of liver cirrhosis complications, being unemployed, and low perceived family support were significantly associated with increasing symptoms severity among this group of patients with liver cirrhosis. Perceived spouse support, marital status and gender made the strongest contribution in explaining severity of symptoms (20. This suggests that these psychosocial variables are most important in explaining severity of symptoms among these patients. On the other hand, somatic factors such as number of liver disease complications made less contribution although this explained about 15. People with a high perception of social support from spouse and family were more likely to have a low perception of severity of symptoms. Although model 1 (Table 7-11) could significantly explain the overall severity of symptoms (p = 0. Three variables were significantly associated with the hindrance of daily activities due to symptoms: gender (b = 0. Being female, low perceived support from spouse and increasing number of liver cirrhosis complications were associated with more limitations in daily life due to symptoms. Interestingly, only gender, perceived spouse support and number of liver cirrhosis complications were significantly associated with both dimensions of symptoms experience, severity and hindrance. Therefore, healthcare providers should consider these factors during the development of intervention programs to treat symptoms among cirrhotic patients. However, many variables associated with severity of symptoms but did not associate with hindrance of symptoms such as marital status, perceived family support and employment status (Tables 7-11 and 7 12). Although model 2 (Table 7-12) predicted the overall hindrance of symptoms significantly (p = 0. An increasing score shows there is increasing perceived availability of social support. This result suggests that Egyptians patients with liver cirrhosis perceive the spouse as the main source of social support followed by family and friends respectively. Married people agreed that their spouse (husband or wife) provided them with different kinds of support. In relation to the perception of adequacy of family support, it was observed that 52. These results suggest that the majority of the patients see a partner to be more helpful than family and friends, and the main source of instrumental and emotional support. However, most of the patients perceive their friends as a source of sharing their joys and sorrows but not as a source for tangible support (like providing services or money). An independent sample t-test was conducted to compare the mean score of perceived social support among males and females. Females were more likely than males to perceive a low availability of support in general and from the husband in particular. Table 7-16 shows the comparison of the perception of social support between the study entire groups according to age. There was a statistically significant association between age and perceived social support (total score) ((f = 5. In addition, the mean score of the subscale of perceived family support was significantly higher among younger than elderly patients 45 (f = 3. The results show that there was a significant association between perceived social support and level of education. The mean score of perceived family support was also lower among illiterates than other groups (f = 7. In terms of general perceived social support (total score), married people and those living in rural areas had higher general perceived social support than unmarried people (t = 4. However, there was no statistically significant difference according to the source of support between married and single people and rural and urban areas. Employed patients had a higher mean score of general perceived social support than the unemployed (t= 4. Also, perceived social support from three sources, spouse, family and friends, was higher among employed than unemployed (t 2. Results show that 262 there was a statistically significant difference only in the subscale of perceived family support between the two disease stages (t = 2. Patients with decompensated cirrhosis had a higher mean score of perceived social support than patients with compensated cirrhosis. There was a significant positive association between the perception of social support and general health perception, suggesting that when social support decreases the general health perception also decreases or vice versa (r= 0. The mean score of the spouse support subscale reporting the highest correlation with the general health perception (r= 0. This means that the social support from a spouse influences the general health perception more than the support of family and friends. However, because this study is a cross-sectional design it is not possible to infer a causal relationship. To develop the regression model, all the socio-demographic characteristics [age, gender, marital status, educational level and employment status, area of residence (dummy code)], and medical variables [disease stage (dummy code), number of comorbidities and number of liver cirrhosis complications] were entered into the regression analysis together as independent factors. Four variables were significantly associated with overall perceived social support [Gender (b = -0. The findings suggest that females, unmarried, unemployed and elderly patients had low perceived social support. The most commonly reported symptoms among these patients were the difficulty of managing time as a result of liver disease, financial problems because of liver disease and memory problems. It was also noted that some symptoms could influence daily activities of these patients more than others could for example; joint pain and depression. Therefore, these symptoms need more attention from healthcare providers when caring for these patients. Bivariate analysis showed that there was a significant association between symptoms experience related subscales and gender, education, employment status, disease stage, complications of liver cirrhosis, and comorbidities. Women, uneducated and unemployed people, and patients with decompensated cirrhosis, multiple complications and comorbidities were more likely to perceive a high severity of symptoms and hindrance in their daily activities due to these symptoms. Singles were more likely to report more hindrance on their daily activities than married patients as a result of symptoms. Moreover, numerous factors significantly influenced the type of symptoms experienced, suggesting that different patients experience different of symptoms. For example, there was a significant difference in the type of symptoms experienced by women and men. Women were more likely than men to suffer from joint pain, right abdominal pain, decreased appetite, depression, jaundice, memory 267 problems and personality change, while men were more likely than women to suffer from sexual problems. In relation to the association between social support and symptoms experience, there was a significant inverse relationship between them. Perceptions of symptoms severity and hindrance of daily activities due to symptoms were significantly associated with social support, particularly from spouse and family. Gender, perceived spouse support and number of liver cirrhosis complications were associated with symptoms severity and hindrance of daily activities due to symptoms. A comparison of social support according to the socio-demographic characteristics found that females were more likely than males to perceive low social support from their partner as well as from friends. In addition, elderly, illiterate and unemployed were more likely to report low perceived social support. Using multiple regression analysis found that age, gender, marital status and employment status were significantly associated with overall perceived social support. Table 8-8 summarises the concepts studied, the measures used, and the psychometric properties. Griffiths and Rafferty (2010) argued that researchers should evaluate the psychometric properties of instruments and not simply believe the claims of others that the tool is valid. Reliability and validity are the key indicators of the quality of an instrument (Kimberlin and Winterstein 2008). Reliability (internal consistency) means that the items within a scale are theoretically homogeneous and are measuring the same construct (DeVellis 2003). Therefore, the alpha coefficient was investigated for the three instruments used in this study. Validity reflects the extent to which the instrument measures what it is intended to measure. Factor analysis is a sophisticated statistical technique that can reveal whether or not the pattern of responses on a number of items can be explained by a smaller number of underlying factors. The two methods make different assumptions about the data and how they should be handled and it is crucial to select the most suitable method to provide answers to different research questions (de Vet et al. The pilot study could not be used for additional validity tests such as factor analysis or known group validity as they usually require a large sample size (Tabachnick and Fidell 2007). Based on the reviewed literature, it was hypothesized that the mean scores of the symptoms severity and hindrance of symptoms subscales of, for example, women and patients with decompensated cirrhosis would be higher than those of men and patients with compensated cirrhosis (Armstrong 2003; van der Plas et al. Suitability of data for factor analysis was checked by determining the adequacy of the sample size and the strength of items intercorrelation. However, the ratio of the number of cases to the number of variables is helpful to decide whether the sample is sufficient. Four to ten cases per item is the rule of thumb to decide the required sample size (de Vet et al. Therefore, a sample size of 401 (without missed data) is sufficient to give a reliable factor structure. The next step was to select the factor extraction technique, in other words determine the smallest number of factors that could be used to measure the interrelations among the variables. The Orthogonal rotation (varimax) method was also selected as a factor rotation method because its solution is usually easier to interpret and report and is the most commonly used (de Vet et al. To assess the most significant loadings in interpreting the factor solution, items that had value 0. Most items showed the highest factor loadings on the original factors (Tables 8-1 and 8-2). Items that cluster on the same components suggest that they are measuring related concepts. Factor 2 included three items (depression severity, depression hindrance and afraid of complications), which may indicate mental health.

Health Care Health Care Systems Asthma is one of the most common medical conditions Delivery and Health afficting both children and adults. In childhood, asthma is more common in boys than girls although it is more common in adult women Key Statements 4 than adult men. Introduction Asthma and allergic diseases account for a signifcant proportion of the chronic illnesses that affict human the Cost of Care for Asthma and Allergic beings. Worldwide, asthma has been described as Rhinitis an epidemic that has increased both in prevalence the economic impact of the diseases being treated must be and incidence over the last 20 years despite improved considered together with the various available interventions pharmacotherapy and environmental control. Yet most providers way, allergic diseases such as rhinitis, food allergy, atopic and healthcare systems fnd it diffcult to incorporate health dermatitis and asthma triggered by allergies have also economic information into clinical and resource decision increased. Despite this information, methods for prevention allergic rhinitis primarily depends on expert opinion rather than evidence-based literature9. Asthma produces a signifcant burden upon the individual, the purpose of this chapter is to review the burden of asthma family and society in terms of physical illness, psychological stress, decreased productivity and cost of care10. It is the and allergic diseases in the human population as treated under various health care systems and the economic burden they major cause of school absenteeism in children, contributing to an estimated 10 million missed school days a year11. It will also review various interventions that have been proposed and how providers are 2003, 10. This number does not include parents who missed work to care for a sick child with asthma. Copyright 2011 World Allergy Organization 140 Pawankar, Canonica, Holgate and Lockey In one study of children and adolescents, more than half were the Scandinavian countries, France, Germany, the United inadequately controlled as measured using the Asthma Control Kingdom, Israel and Canada use government funded and in Test. Such inadequately controlled asthma signifcantly affected some cases government-delivered healthcare models. The highest asthma hospitalization rates among Another confounder to identifying the actual cost of care for children were for those aged 0-4 years. In 2003, 4,055 persons asthma and allergic diseases is the price of pharmaceuticals. Other countries that 42% were indirect costs such as child care expenses, restrict collective bargaining for discounted drug prices tend to transportation and loss of workforce participation13. More have much higher pharmaceutical costs which can contribute a recent estimates of the annual cost of asthma are nearly high proportion to the total cost of treatment for allergic diseases. Healthcare systems that rely on government funded institutions that are subsidized by taxes, In addition to asthma, it has been estimated that 1 in 5 Americans, may report lower costs than systems in which hospitals tend to or 50 million persons, experience allergies, including nasal be for-proft entities. As a result, it is very diffcult to determine allergies, food allergy, drug allergy, atopic eczema, and insect the actual cost of care for a patient with asthma and other allergy. The incidence of allergic diseases has been increasing allergic diseases given the extreme heterogeneity of healthcare in all age groups for the past 20 years. Some surveys even One way to measure true costs would be to develop normalized suggest that atopic eczema imposes an economic burden with metrics that correct for the type of delivery system in which overall costs similar to those for treatment of asthma15. Though this has not been systematically annual cost of such allergies is estimated to be nearly $7 billion. Corrections for variable use of pharmaceutical agents the main diffculty with determining the global cost of care depending on costs and accessibility would also have to be for patients with asthma and allergic conditions is that care weighted in this model in order to come up with a consistent is delivered in countries with different healthcare delivery cost for care delivery. These types of healthcare systems include: direct or out-of-pocket payments by patients for their care, government Another confounder is the cost of overheads in managing provided care paid for by taxes, public health insurance with healthcare delivery. Countries with single-payer systems services provided by private entities voluntary or private health tend to have overhead costs that are relatively low because insurance usually provided by employers, and healthcare reimbursement involves a single payment system. In the United States where multiple health plans typically pay for the United States utilizes an employee/employer-provided care, each provider must rely on workers who are dedicated private insurance model for many of its working citizens. Health Seniors and the poor are usually covered by government plans themselves have a pool of personnel that receive the paid Medicare or Medicaid programs using private providers claims and determine whether payment will be made. Though this cost is not successful self management by the patient of their usually included in the individual cost for treatment of specifc allergic condition medical conditions, it should be if a complete accounting of the Key features for optimal health care professional/patient interactions: actual costs of care is to be determined. This requires that there be optimal training access to professional advice when self management necessitates it of health care professionals as well as regular review of their competencies, enforcement of practice standards according to evidence-based internationally recognized and respected Summary guidelines17 and adequate resources for basic investigations18. Given the huge global burden caused by asthma and allergic Perhaps the most important aspect of care consists of a patient diseases, it is clear that health care systems need to address centered approach which elicits patient expectations, fears and the burden aggressively and in a cost-effective manner. In addition, providers need some countries and by primary care physicians in many others. Ideally, this everyone, whether a primary care nurse a lay educator or a care should be accompanied by outcomes measures that can specialist. The value of guidelines in the delivery of this care be implemented by the providers so that they can learn from cannot be underestimated and are summarized in Table 1, their experiences. If these integrated, evidence-based systems but all should be designed to be utilized within a partnership of care can be created, the burden of allergic diseases will likely of care between patients and health care professionals that decrease substantially.

The the world and illustrates that for some countries the problem undergraduate training should be able to provide a working is greater than for others. However even in low prevalence knowledge of the common allergic disorders including allergic countries increases are being observed. This includes lactose and other through providing better training for undergraduate medical sugar intolerances, scromboid fsh poisoning, and hereditary students, primary care physicians and generalists, as well as angioedema. A It is also important that undergraduate medical students are summary of the present situation is highlighted in the White made aware of the global and regional epidemiology of allergic Book Chapter 1, the Practice of Allergy. This for global education in Allergy and has published 2 position would include an understanding of the value and indications for statements which provide guidelines for training in Allergy for diagnostic tests such as skin prick and in vitro IgE measurement Medical students3 and for practicing clinicians4. Age-specifc use of medications such as those not usually taught in most medical schools as a separate delivered by inhalers, and monitoring of progress and response subject and thus the teaching tends to be fragmented and to treatment should be included in the program. Furthermore, food allergy concise documents should be read by all students training in and intolerance, drug allergy and hypersensitivity, oral allergy medicine and other health professions at an undergraduate level. This includes lactose and other sugar Programs can be designed to be applicable to students with intolerances, scromboid fsh poisoning, and hereditary a wide range of background skills who require a detailed angioedema. They will also have developed skills in the of new ideas use of computing applied to healthcare. This is most easily achieved by a blended learning Food scientists need to be made aware of the dangers of structure where face-to-face teaching is provided in short blocks hidden food allergens and the medical effects resulting from and the majority of learning is web-based. Proper labeling benefcial to all education as re-usable teaching objects can be should be mandatory for all processed foods. The World Allergy Allied Health Workers Organization Web site provides education materials which can Allied health workers play an important role in the care of be used for this purpose. However, in most parts of the world, allergy is not included in their training curricula. Wider Education Allied health workers particularly in need of allergy education the distribution of asthma and allergies according to race and include pharmacists, nurses, dieticians, food scientists socio-economic status is infuenced by large inequalitiesin society, and paramedics. These professionals need to learn about since prevalence rates appear to be high in urban and minority the basic underlying mechanisms of the allergic response populations. These patients are at higher risk to develop allergy and the presentation of common allergic diseases such as and/or asthma and therefore worthy of more focused asthma and asthma, rhinitis, food allergy, drug allergy, atopic dermatitis, allergy education. In particular they should learn about account their diversity, is therefore mandatory with information the importance of specifc allergy diagnosis. Behavioral factors and Pharmacists should be made aware of new global guidelines family social support also infuence levels of treatment adherence, for management of asthma and rhinitis, as they are often the decisions to engage in risk reduction, and care-seeking. The frst health care worker to be approached by the patient, and of socio-economic burden of allergy and asthma can only be the dangers of sedating antihistamines; they should discourage reduced if patients and their families are better informed about the use of these medications for allergic rhinitis management. It is fundamental that new scientifc evidence They need to be educated in the appropriate use of generic Copyright 2011 World Allergy Organization 146 Pawankar, Canonica, Holgate and Lockey relevant for each target group is disseminated in a language they and education in which a very wide range of bodies including can understand and in a user-friendly fashion. Patients need government departments, non-departmental public bodies, simple information on medications; costs and reimbursement; local authorities and charities. All these organizations play a self-treatment; nutrition; environmental factors both indoor and role in disseminating information and advice. In this feld, future studies should focus on and asthma, in order to reduce their burden in all regions. This optimizing the potential benefts of educating high risk patients problem requires an integrated approach and moreover, when since they are at the highest lethal risk and often consume a directives are made at a global level, they should be harmonized disproportionate amount of health care resources. Food product labeling, although improved, education in allergy at medical schools around the often remains ambiguous. Vague defensive warnings on labels world is a major unmet need which could provide better for consumers with food allergy can lead to dangerous confusion and improved levels of care for allergy sufferers, and in and an unnecessary restriction of choice. Social diffculties caused particular to the millions who do not have access to the by having a food allergy can sometimes make sufferers reluctant services of allergy specialists. Therefore product labeling the interaction between the environment and susceptible needs to be more accurate, and clearer. Parents of allergic children genes in the onset and progression of allergy and asthma, and allergy sufferers should be educated on optimal avoidance in order to reduce the disease burden in all regions. This should be based on the and comprehensively trained in practical allergen management.

This allows the option visceroabdominal disproportion, associated anomalies, or of nonoperative reduction for infants for whom it is suitable complications such as necrotizing enterocolitis.

However, Association of Pediatric Surgeons Network also used the results of this national observational study demonstrate no population-based data from 16 centers with similar success clear benefits of either technique and may thus go some way in data collection. Nonstatistically significant but potentially clinically closure techniques are mostly successful in bringing about significant increases in rates of wound infection and fascial apposition. This, in view of the fact that only necrotizing enterocolitis were observed in the complex approximately half of all cases are managed with intended group. Interestingly, all the neonatal deaths occurred in operative primary reduction and defect closure may indicate the simple group, although this was not statistically sig that visceroabdominal disproportion is largely correctly nificantly different because of the small numbers involved. We identified a neonatal the subsequent success; thus, these rates cannot be validly mortality rate of 6 (2%) in the simple group which is similar compared statistically. However, the conversion rates to other studies [12] and which is usually attributed to importantly suggest that no single approach is universally associated anomalies or complications of initial surgical applicable, and therefore, a rescue strategy is needed by all intervention. It seems that a clinical pathway is emerging in settings, this rate is much higher and is attributed to sepsis, which a nonoperative technique may be adopted with shock, and intestinal ischemia [19], this study suggests conversion to an operative strategy if difficulties are that this mortality rate could still be reduced further in the Contemporary surgical strategies for gastroschisis 1815 United Kingdom.

Anaerobic exercise is a short burst of high intensity effort, such as a sprint for a bus. However, only a small amount of glucose is present in the muscle cells and this is used up within a few minutes of anaerobic exercise. McArdle disease is caused by the lack of the muscle glycogen phosphorylase enzyme in muscle cells. In McArdle people, muscle glycogen phosphorylase is either absent or not functional. The short term lack of glucose causes tiredness and stiffness in muscles of McArdle people when they carry out anaerobic exercise (Rommel et al. A period of rest is necessary because these other methods are slower to produce energy than glycogenolysis (the method which normally involves muscle glycogen phosphorylase). This can lead to breakdown of muscle cells (rhabdomyolysis) and muscle cramps (contractures), both of which cause McArdle people to experience muscle pain. Following rhabdomyolysis, the components of the broken muscle cells are released into the bloodstream. The components of the broken muscle cells are transported through the bloodstream to the kidneys. Myoglobin is transported in the bloodstream to the kidneys, where it is removed from the body in the urine, resulting in dark red/cola coloured urine (known as myoglobinuria or proteinuria). A rare, but serious effect of extreme muscle damage is that broken muscle cells may block the filtration system of the kidneys, preventing them working, and resulting in kidney failure (Martin et al. McArdle disease is caused by the absence of the muscle glycogen phosphorylase enzyme (Mommaerts, 1956; Schmid et al. An enzyme is a protein which has a special function of changing or breaking down one compound to another. The muscle glycogen phosphorylase enzyme breaks down glycogen into glucose-1-phosphate. If a mutation occurs in the enzyme which prevents it from functioning, it will result in an inability to break down glycogen and its components to form glucose. The major symptom of every glycogen storage disease is an intolerance to exercise. Phosphorylase b kinase is essential for activation of the muscle glycogen phosphorylase enzyme. McArdle disease is named after Dr Brian McArdle, the British family doctor who first published a paper describing a patient with the disease. In 1951, Dr McArdle described a 30 year old male patient for whom light exercise caused pain in the muscles, and continued exercise led to weakness and stiffness. The pain would force the patient to stop and rest, but it was noted that after a period of rest, the patient was then able to exercise further. Dr McArdle realised that after exercise the lactate level of the patient did not increase as expected, and that glycogenolysis was incomplete. However, if the McArdle person rests for a short period, the muscles can get energy from glucose in the blood or from other sources, such as fat which is stored in the body. The internet has also enabled people with McArdle disease to compare symptoms and advice and to provide support with others around the world through online patient support groups. In the longer term, many different avenues for treatment are being considered, including correcting the expression of muscle glycogen phosphorylase which contains a mutation, or replacing it with the brain glycogen phosphorylase enzyme. Outside of school, many McArdle children and adults will have developed coping mechanisms to allow themselves to rest without other people noticing.

A parasternal long-axis view of a patient with severe mitral stenosis due to rheumatic heart disease. During systole, the mitral valve is closed and blood is expelled through the open aortic valve (single arrow). During diastole, opening of the mitral valve is restricted, and a characteristic bowing of the mitral valve (arrows) is observed. Of all the valvular lesions, mitral stenosis is the least com monly encountered in developed countries but still remains a common problem in many parts of the developing world. Mitral regurgitation is much more commonly observed than mitral stenosis and can be due to severe mitral valve prolapse, endocarditis of the mitral valve, myocardial ischemia, or rheumatic valvular disease. Like aortic regurgitation, Doppler techniques are used to identify the high-velocity turbulent jet. However, in mitral regurgitation, the high-velocity jet is observed in the left atrium, emanates from the mitral valve, and occurs during ventricular contraction (systole). A wide necked jet that encompasses a larger portion of the left atrium is character istic of severe mitral regurgitation. A high-velocity jet is observed in the left atrium (arrows), emanating from the mitral valve. A wide necked jet that lls a large portion of the left atrium suggests severe mitral regurgitation. Doppler evaluation of the tricuspid valve is frequently used to assess right-sided cardiac pressures. The relative pres sure difference between two chambers can be estimated by using a simpli ed formula of the Bernoulli equation: 2 P = 4V where P is the pressure difference in mm Hg and V is the velocity between two cardiac chambers in m/s. Using the simpli ed Bernoulli equation, the difference between right atrial pressure and right ventricular pressure reaches 56 mm Hg during systole. In transesophageal echocardiography, the trans ducer can be placed on a probe designed to enter the esophagus. In intracar diac echocardiography, the transducer can be placed on a catheter designed to enter the heart itself via one of the central veins (usually the femoral vein) and advanced via the inferior vena cava into the heart. Imaging from a trans ducer located adjacent to the heart (transesophageal echocardiography) or from inside the heart (intracardiac echocardiography) produces images with exquisite detail and resolution. In tricuspid regurgitation, the high-velocity ow is recorded during systole and not in dias tole (Dias). The simpli ed Bernoulli equation can be used to estimate the pressure difference between the right ventricle and right atrium from the peak velocity recorded from the tricuspid regurgitation signal (3.
