Echocardiographic (ECHO) findings in 211 consecutive examinations performed at Eldoret Medical Services from August 1992 to May 1994 were analysed. Most patients were referred by physicians from Eldoret and from the surrounding hospitals for assessment of heart failure or a heart murmur. Thirty three echocardiograms were judged as being normal and 177 abnormal. Of the abnormal ECHOs, congenital heart disease accounted for 38.4% while rheumatic heart disease accounted for 40.7%: Of the 68 patients with congenital defects, 21 (30.1%) had ventricular septal defects; 19 (27.9%) persistent ductus arteriosus; five (7.5%) mitral valve; four (5.9%) tetralogy of Fallot; and three (4.4%) atrial septal defects. In addition, there were two (3.0%) patients each with complete atrio-ventricular septal defects, tricuspid atresia, complete transposition of the great arteries, truncus arteriosus, single ventricle and bicuspid aortic valve. Of the 67 patients with uncomplicated rheumatic heart disease, mitral valve involvement alone was seen in 39 (58.2%), mitral and aortic in 26 (38.8%) and aortic valve alone in two (3.0%). Rheumatic heart disease was complicated by bacterial endocarditis in five patients. Nine patients had pericardial effusion. The possible role of colour-flow ECHO as a feasible, non-invasive and, in the long term, cost-effective means of allowing for early detection and timely institution of secondary prophylaxis while rheumatic heart disease is still asymptomatic is highlighted.

Heart disease is a common cause of morbidity in end-stage renal disease (ESRD) patients. The management of heart disease in these patients requires a multidimensional approach to the management of heart failure, coronary disease, and arrhythmias, and to risk factors such as hypertension, anemia, secondary hyperparathyroidism, and electrolyte/acid-base disturbances. Coronary artery disease management includes use of antianginal drugs and revascularization of coronary arteries with angioplasty +/- stent placement or coronary artery bypass grafting. The long-term outcomes of these procedures need to be assessed and improved. Hypertension occupies a major role in the pathogenesis of heart disease in ESRD, and early and adequate control of hypertension is likely to have a major impact on the progression of cardiac disease. This entails the achievement of optimal volume status, combined with the appropriate use of antihypertensive agents such as calcium channel blockers, beta-blockers, angiotensin-converting enzyme (ACE) inhibitors, vasodilators, alpha-blockers, and central sympatholytic drugs. In ESRD patients, specific dialysis-related complications such as intradialytic hypotension and pericardial effusion may have additional effects on cardiac function and require attention. The choice of dialysate composition and membrane may influence clinical outcomes with specific effects on cardiac performance.

While Fontan operation is considered a palliative procedure for the treatment of complex congenital heart disease, its morbidity and mortality are certainly not negligible, especially in high-risk patients. In our opinion, a bidirectional cavo-pulmonary anastomosis with an additional source of blood flow to the lungs (Blalock-Taussig shunt, pulmonary artery banding, native pulmonary stenosis) represents a valuable surgical option in this subset of patients. From November 1992 to September 1994, sixteen patients with complex congenital heart disease underwent bidirectional cavo-pulmonary anastomosis, leaving an additional source of blood flow in place (modified Blalock-Taussig shunt in 9 cases, pulmonary artery banding in 6 cases, native pulmonary stenosis in 1 case). Eight of these patients (50%) were reinvestigated after a mean follow-up of 15.7 months (range 1-26 m). It has been possible to differentiate two types of pulmonary blood flow, according to the nature of the additional flow source; in the case of cavo-pulmonary anastomosis and pulmonary artery banding or pulmonary stenosis, pulmonary blood flow was pulsatile and evenly distributed to both lungs, while in the case of bidirectional cavo-pulmonary anastomosis and Blalock-Taussig shunt, pulmonary flow was non pulsatile and asymmetric (angiographic criteria). There were no hospital deaths. Late mortality was 12.5% (2 pts) due to worsening of atrioventricular valve regurgitation. In one of these two patients, prolonged pleural and pericardial effusion occurred. In conclusion, bidirectional cavo-pulmonary anastomosis with an additional flow source is a good alternative to classic or fenestrated Fontan operation in the treatment of complex congenital heart disease. The best results are obtained with an additional flow source represented by pulmonary artery banding or pulmonary stenosis, due to pulsatility and uniform distribution of blood flow in the pulmonary district. Morbility and mortality compare favorably with the rates observed in classic or fenestrated Fontan operation.

Kawasaki syndrome (KS) is an acute, sometimes fatal vasculitis of young children. KS has replaced acute rheumatic fever as the most common cause of acquired heart disease in children in the United States. The illness is manifested by prolonged fever, conjunctival injection, enanthem, exanthem, erythema and swelling of the hands and feet, and cervical adenopathy. These acute features of illness are self-limiting, but coronary artery abnormalities occur in 20% of untreated patients. The etiology of the illness is unknown, but its clinical and epidemiologic features are most consistent with an infectious cause. Common cardiovascular manifestations of the illness include myocarditis, pericardial effusion, and coronary artery aneurysm formation. Treatment with intravenous gamma globulin (IVGG) and aspirin within the first 10 days of illness reduces the prevalence of coronary artery abnormalities from 20% in those treated with aspirin alone to 4%. Patients who develop coronary artery aneurysms, particularly those who develop giant coronary artery aneurysms, may suffer myocardial infarction secondary to thrombosis or stenosis in the abnormal vessel. Additional research to determine the cause of KS is urgently needed to allow for improved diagnosis, more specific therapy, and prevention of the disorder.

As more effective therapies have produced longer survival times for human immunodeficiency virus (HIV)-infected patients, new complications of late-stage HIV infection including HIV-related heart disease have emerged. Almost any agent that can cause disseminated infection in patients with acquired immunodeficiency syndrome (AIDS) may involve myocardium, but clinical evidence of cardiac disease is usually overshadowed by manifestations in other organs, primarily the brain and lungs. Cardiac abnormalities are found at autopsy in two-thirds of patients with AIDS, and more than 150 reports of cardiac complications have been published. Cardiac involvement in HIV disease includes pericardial effusion, myocarditis, dilated cardiomyopathy, and/or endocardial involvement at any stage of the disease. This review deals with all the cardiac manifestations of AIDS and serves to highlight two problems and one indication. First of all, there are very few clinical studies. Current knowledge is based almost exclusively on echocardiography and autopsy studies. Observational or clinical trials would be useful. Second, there exists very poor information on the impact of treatment; and epidemiologic and clinicopathologic studies are mandatory for obtaining detailed data concerning the mechanisms of myocardial damage in AIDS. Finally, because cardiac complications are often clinically inapparent or subtle in the initial stages, periodic screening of HIV-positive patients by electrocardiogram and echocardiogram is probably indicated. In addition, AIDS may also provide the opportunity to gain insights into the pathogenesis of little understood cardiac diseases such as lymphocytic myocarditis and dilated cardiomyopathy.

A case is described of a 54 year old woman who had acute pericarditis with large exudative effusion accompanied by severe right and left ventricular failure. The patient was finally diagnosed with carcinoid heart disease from an ovarian carcinoid teratoma. She was treated with octreotide--a somatostatin analogue--followed by radical surgical resection of the neoplasm. At one year follow up only mild carcinoid tricuspid regurgitation remained. Only 16 cases of carcinoid heart disease from an ovarian primary have been described in literature. Moreover clinically manifest acute, nonmetastatic pericarditis and left heart failure are not considered as possible presentations of carcinoid heart disease, whatever the origin. In a recent series a small pericardial effusion was considered an infrequent and unexpected echocardiographic finding in carcinoid heart patients. One case of "carcinoid pericarditis" has previously been described as a consequence of pericardial metastasis. Left sided heart involvement is usually caused by bronchial carcinoids or patency of foramen ovale; both were excluded in the case presented.

In the ICU, both transthoracic and transesophageal echocardiography can assist in the acute management of a number of different disorders. In hypotensive patients, echocardiography helps distinguish between cardiogenic shock (resulting from acute myocardial infarction), septic shock, and circulatory shock (associated with a reduction in circulating blood volume); it can also help determine whether pericardial effusion or obstruction to valvular flow is producing the hypotension and suggesting pulmonary embolus. Other roles for echocardiography include differentiating left- and right-sided heart failure, assessing the extent of pericardial disease, diagnosing disorders of the thoracic aorta, and evaluating traumatic heart disease.

A case of metastatic colonic adenocarcinoma invading the left atrium is reported in a patient with clinical signs of cardiac tamponade. The intracavitary extension of the tumour was clearly demonstrated by contrast enhanced CT. As CT plays an important role in the evaluation of patients with intrathoracic masses, intravenous contrast medium is recommended in those cases with associated clinical symptoms of heart disease or pericardial effusion. Its use may establish the diagnosis of cardiac involvement.

Although formation of an aortic root abscess is a frequent complication of aortic valve endocarditis in adults, this complication has been rarely observed in children. In the majority of cases it has been described in children without underlying congenital heart disease. Due to the rarity of this complication, diagnosis and treatment is frequently delayed in childhood. We report a 2 1/2 year old girl who developed pericardial effusion in the course of pneumonia. Echocardiographic examinations, which were performed because of the pericardial effusion, revealed after 6 days the development of a cystic structure posterior to the aortic root. There was a perforation of this aortic root abscess to the left ventricular outflow tract; the aortic and mitral valves however were normal without endocarditic vegetations. Surgery was performed on the 10th day following a rapid increase in the size of the abscess. During surgery the abscess was drained and the perforation to the left ventricle was closed with direct sutures. Intraoperative transesophageal echocardiography confirmed a good surgical result. Blood cultures remained negative; in the material from the abscess however we found staphylococcus aureus. The postoperative course was uneventful. Our case demonstrates the necessity of detailed and repeated echocardiographic examinations in children with possible symptoms of bacterial endocarditis (in our case pericardial effusion) as well as the requirement of cultures of the abscess for identification of the infective organism. Intraoperative transesophageal echocardiography allows exact description of an aortic root abscess, its relation to other cardiac structures and immediate evaluation of the surgical result.

The frequency of pericardial involvement in Systemic Sclerosis (SSc) is high on autoptic or echocardiographic studies, but the clinical recognition of pericarditis with or without effusion is rare. We describe a case of a 71-year-old female with no previous history of heart disease, who presented with a large pericardial effusion and tamponade that required pericardial drain. She had suffered from Raynaud's phenomenon since 25 years. Six weeks after hospital discharge she complained of skin hardening on left leg. Pericardial tamponade is a very rare manifestation of SSc and occurs both early or late in the course of the disease, but in our case it preceded the recognition of scleroderma. We have only identified two other cases of pericardial effusion preceding cutaneous involvement in scleroderma.
