An 18-year old white youth presented with severe right heart failure and was found to have an obliterated and funnel-shaped right ventricle, massive tricuspid regurgitation, and mitral regurgitation. The haemodynamic findings were those of cardiomyopathy with obliteration on the right side. He underwent surgery consisting of decortication and peeling off of a thickened right ventricular endocardium, tricuspid valve replacement, and mitral valve repair. After surgery there was pronounced haemodynamic as well as clinical improvement. The pathological picture was that of constrictive endocarditis. We recommend this method of treatment for patients with obliterate cardiomyopathy on either side of the heart.

A patient with alpha-haemolytic streptococcus endocarditis on a ventricular septal defect is described. The disease spread to involve both tricuspid and pulmonary valves which were largely destroyed. The patient developed severe right heart failure with pronounced rise in right atrial pressure. This led to right-to-left shunting through the foramen ovale with systemic embolization. She was successfully treated by operative closure of the defects and double right-sided valve replacement.

Tricuspid valvulectomy without prosthetic replacement has been advocated as a life-saving measure in the treatment of Pseudomonas endocarditis of the tricuspid valve. This report describes the hemodynamic data obtained in 10 patients before and after removal of the tricuspid valve. Seven patients remained free of carciac decompensation, but right heart failure developed in three. Analysis of the preoperative data did not permit differentiation of these two groups of patients.

A 26 year old Saudi man with features of both Loeffer's endocarditis and endomyocardial fibrosis presented with mild symptoms and pulmonary emboli. Echocardiographic examination showed obliteration of the right ventricular apex by an attached mass. The results of haemodynamic studies were somewhat abnormal and medical treatment was started. Despite anticoagulation with warfarin the patient's condition deteriorated rapidly over a four month period after a further episode of pulmonary embolism and the development of pulmonary hypertension. Two haemodynamic studies performed four months apart were typical of pulmonary hypertension and later right ventricular failure; they showed none of the characteristics of restriction. Pulmonary embolectomy was attempted but there was no cleavage plane between the organised thrombi and the endothelium of the pulmonary artery. The patient died of severe pulmonary hypertension and right ventricular failure several days after operation. Surgical intervention in the early stages of right-sided endomyocardial fibrosis might have prevented the development of pulmonary embolism and pulmonary hypertension.

A successful repair of infective endocarditis of the tricuspid valve in a drug abuser is reported. A 25-year-old woman with a history of drug addiction was referred to our hospital complaining of high fever despite antibiotic therapy. Blood cultures showed staphylococcal septicemia, and echocardiography revealed large vegetations attached to the tricuspid annulus and massive regurgitation of the tricuspid valve. Blood studies showed renal failure and hematological abnormalities due to septicemia and right ventricular failure. Excision of the vegetation and the posterior leaflet was performed along with annuloplasty (Kay's procedure). The patient's postoperative course was uneventful and subsequent echocardiographic examination disclosed no evidence of recurrence, and insignificant tricuspid valvular regurgitation. Local excision of vegetation and leaflet repair by annuloplasty may be performed in cases with well-circumscribed vegetation and minor leaflet damage.

A case of infective endocarditis of the tricuspid valve is described in a young female patient with no history of intravenous drug abuse. The patient suffered from symptoms of septic emboli of the lung and right heart failure. She was ultimately treated by tricuspid valve replacement. There was no recurrence of symptoms following surgery.

Since September 1970, we have operated on 55 patients with intractable right-sided endocarditis. All patients were addicted to heroin. Fifty-three underwent tricuspid valvulectomy without replacement and in addition two had pulmonic valve excision. Twenty-four patients (49%) returned to their drug addiction. Six patients (11%) required prosthetic heart valve insertion 2 days to 13 years later for medically refractory right-sided heart failure, and four of these died. Overall, 16 patients (29%) died, six (11%) within 45 days after the tricuspid valvulectomy. One (2%) of these deaths was related to the operation and five were due to uncontrollable infection. Ten (18%) deaths occurred 9 months to 13 years after the tricuspid valvulectomy. Nine were due to drug addiction and one to progressive right ventricular failure 2 months after prosthetic heart valve insertion and 10 years after the initial valve removal. Of the 39 patients who are alive, 37 (67%) have not required prosthetic heart valve insertion. From our observations we reached the following conclusions: (1) Drug addiction is a recurrent and lethal disease. Among these patients, tricuspid valvulectomy without replacement is the operation of choice for the management of intractable right-sided endocarditis; (2) after tricuspid valvulectomy without replacement, only six of 55 patients (11%) had required prosthetic heart valve insertion to control medically refractory right-sided heart failure; (3) in a small percentage of patients the absence of the tricuspid valve may lead to severe and permanent impairment of right ventricular function.

Ten cases of right-sided infective endocarditis (IE) were recorded in a retrospective study over a 5 year period (1984-88). In 8 cases, IE complicated known congenital heart disease. One patient was followed up for rhumatic valvular disease and in the remaining case, IE seemed to have occurred on a normal valve. The inclusion criteria were based on the clinical signs: prolonged pyrexia, the finding of a new murmur or a change on cardiac auscultation, and eventually, the occurrence of a complication (7 cases). The commonest complications were right ventricular failure and pulmonary embolism. A portal of entry was found in 5 cases: dental infection in 3 cases, osteomyelitis in 1 case and an abscess on the right leg in 1 case. Blood cultures were positive in 5 cases and grew a staphylococcus aureus on each occasion. Two-dimensional echocardiography showed vegetations in 9 cases. The short-term outcome was satisfactory. There were no fatalities and 5 patients underwent surgery.

Thirty-eight cases of infective endocarditis (IE) were observed between 1976 and 1989 (1.3% of all cardiac disease). Thirty two cases were retained for study based on Von Reyn's criteria: 28 native valve endocarditis (27 left and 1 right heart valves) of which 18 occurred on previously undiseased valves (56.3%); 4 cases of left heart prosthetic valve endocarditis. The average age of the patients was 27.5 +/- 14 years and the group comprised 24 women and 8 men (p less than 0.001). Blood cultures were negative in 13 cases, revealed a Gram negative pathogen in 8 cases, a streptoccocus in 3 cases. Blood cultures were not performed in 2 cases. The IE was acute in 18 cases (56.7%) and subacute in 14 cases (43.7%). The dominant clinical signs were of massive and sometimes acute valvular regurgitation (mitral: 21 cases; aortic: 10 cases; mitral and aortic: 3 cases; tricuspid: 1 case). Twenty-six patients had cardiac failure (81.2%): LVF: 15 cases, congestive cardiac failure: 10 cases, RVF: 1 case. The other complications were embolic: cerebral (3 cases), mesenteric (1 case), pulmonary (4 cases). Antibiotic therapy was prescribed in all patients; surgery was required in 9 cases. There were 12 fatalities (37.5%), 10 in the medically treated group and 2 in the surgical group (p less than 0.05). The results show that the prognosis of IE in underdeveloped regions remains poor. Effective strategies of early diagnosis and treatment are urgently required to reduce the high mortality. Prophylaxis of IE should commence with measures to counter the portals of entry of the pathogens and the valvular sequellae of acute rhumatic fever.

Six cases of isolated tricuspid valve endocarditis in young women are described. Preceding genital sepsis was a predisposing factor in 4 patients. Cardiac signs are unusual at presentation, rendering the diagnosis difficult. Pleuropulmonary manifestations are the predominant findings, while overt signs of tricuspid insufficiency and right heart failure occur late in the disease. Staphylococcus aureus is the pathogen most commonly found and requires energetic treatment for a minimum of 4 weeks. The value of echocardiography in establishing an early diagnosis is stressed. Persistent sepsis constitutes a major indication for surgery.
