A 13-year-old girl presented with infective endocarditis of the tricuspid valve related to a residual ventricular septal defect. Antibiotic therapy produced a satisfactory initial improvement, however, subsequent deterioration with uncontrolled infection, in spite of alterations in the antibiotic regime, necessitated surgical intervention. Because the endocarditis was localized to the septal leaflet, management by excision of this leaflet and annuloplasty was possible and resulted in a rapid and sustained clinical improvement with no evidence of significant residual valvar incompetence. The medical management of infective endocarditis requires bacteriological assessment to ensure that the drugs and dosages selected are appropriate and adequate for the causative organism. Early operation may be required for uncontrolled infection or cardiac decompensation; in tricuspid endocarditis secondary to a ventricular septal defect, the operation described permits removal of infective tissue while retaining valvar competence.

Fourteen consecutive cases of ventricular septal defect (VSD) associated with aortic insufficiency (AI) are considered from a pathological and surgical point of view. In one operated patient the AI was due to previous endocarditis with perforation of both coronary cusps. In the remaining 6 cases one or 2 aortic cusps were prolapsed. Closure of VSD was accomplished with teflon patches in 6 and with direct suture in one. The aortic valve was replaced with an aortic Bjork-Shiley prosthesis in one case, and simple valve reconstruction was carried out in the remaining 6 patients. There was no mortality. In 3 patients who presented with residual AI one month after operation, the cardiothoracic ratio and the electrocardiogram have nevertheless returned progressively to normal limits. The authors favor correction at preschool age on the principle that early closure of the VSD may prevent or control the AI. However, in small children in whom the severity of AI may suggest the necessity for valve replacement, the operation is postponed as long as possible to avoid functional prosthetic stenosis later in life.

The surgical treatment of acute heart failure is limited to cases of pressure or volume overload. Acute valvular regurgitation due to active endocarditis or to prosthetic dysfunction is a classic example of failure which can be cured by restoring valvular competence. Acute pressure load is mostly caused by prosthetic dysfunction or pulmonary embolism; therapy is aimed at removal of the causative agent. Coronary heart disease can cause heart failure by volume overload: acute mitral incompetence or ventricular septal defect lend themselves to surgical correction. In the surgical treatment of acute heart failure maximal attention is devoted to optimal timing of surgery, anesthetic management and postoperative care. Careful attention to the function of the right and left ventricle and combination of catecholamines, afterload reducing agents and volume loading together with respirator support have considerably improved the surgical results. Acute pump failure due to coronary insufficiency and infarction is less amenable to surgical treatment, with rare exceptions of emergencies during coronary angiography and percutaneous dilatation. The intra-aortic balloon pump is the only method of mechanical circulatory assistance which has reached widespread clinical acceptance. The best results are achieved in conjunction with surgery: either as cardiac support in inherently reversible postoperative heart failure or as the means of circulatory stabilization prior to surgery. Ventricular assist devices are still in the experimental stage: their use has been sharply curtailed by the virtual disappearance of the postoperative low output syndrome. In selected cases of end-stage cardiomyopathy cardiac transplantation is nowadays performed with acceptable survival (70% at one year after surgery). Both orthotopic and heterotopic transplantation (transplanted heart in parallel with the natural one) give comparable results, but the procedure is still very restricted due to the lack of donors, multiple contraindications and lack of suitable heart preservation techniques.

Small diameter aortic valve bioprostheses are associated with resting ventriculo-aortic pressure gradients of 10 to 35 mmHg. In order to avoid this factor favouring degradation of left ventricular function and early deterioration of the bioprosthesis, we enlarged the aortic ring when the diameter was less than 23 mm in patients considered unsuitable for long-term anticoagulation. The surgical technique involved incising the annulus from the postero-lateral commissure to the anterior mitral leaflet and implanting a Dacron patch lined with pericardium. Nine patients aged from 10 to 70 years (average 22 years) underwent aortic valve replacement with a Carpentier-Edwards bioprosthesis associated with enlargement of the aortic ring, between June 1979 and December 1981. The mean follow-up period is now 18 months (range 9 to 39 months). One patient has been lost to follow-up. Before surgery, 6 patients were in Stage III and 3 patients in Stage IV of the NYHA classification. There were 4 patients with pure aortic regurgitation with valve prolapse, 1 patient with aortic regurgitation due to endocarditis, and 4 patients with mixed aortic valve disease. The underlying disease was rheumatic in 6 cases, congenital in 2 cases and infective endocarditis in 1 case. The mean diameter of the aortic ring before enlargement was 19 mm. After the procedure, it increased to 23,8 mm, so enabling the implantation of no 23 and no 25 bioprostheses. Three patients had associated mitral regurgitation, 3 patients had mixed mitral valve disease, 1 patient had a membranous VSD with infundibular stenosis, and 1 patient had subvalvular aortic stenosis.(ABSTRACT TRUNCATED AT 250 WORDS)

Two children with ventricular septal defect and tricuspid valve endocarditis are presented. One of them had ongoing endocarditis with septic pulmonary embolism, the other suffered from florid endocarditis presumably 3 months before the study. M-mode echocardiography showed echodense masses in the right ventricular outflow tract in one and anomalous systolic anterior movement of tricuspid valve tissue in the other patient. Sectorechocardiography demonstrated in both children abnormal masses originating from the tricuspid valve and extending into the right ventricular outflow tract. Surgery confirmed endocarditic vegetations and destructions of the tricuspid valve. After operative closure of the ventricular septal defect and reconstruction of the tricuspid valve both children are well. Our experience underlines the usefulness of echocardiography, especially sectorechocardiography, in demonstrating endocarditic vegetations originating from the tricuspid valve.

The gross surgical pathologic features of the aortic valve were reviewed in 225 patients who had had clinically pure aortic insufficiency and aortic valve replacement at our institution during the years 1965, 1970, 1975, and 1980. The four most common causes of aortic regurgitation were postinflammatory disease (46%), aortic root dilatation (21%), incomplete closure of a congenitally bicuspid aortic valve (20%), and infective endocarditis (9%). Other causes of aortic incompetence in our study included ventricular septal defects (2%) and quadricuspid aortic valves (1%); the cause was indeterminate in 1%. The mean age of patients at valve replacement was approximately 50 years for all etiologic factors except a ventricular septal defect. All forms of aortic insufficiency were much more common in male than in female patients, except the postinflammatory and indeterminate types, which occurred approximately equally in both sexes. Moreover, the incidences of postinflammatory disease and aortic root dilatation changed appreciably with time. Before 1980, their incidences were 51% and 17%, respectively, but during 1980, they were 29% and 37%, respectively. Accordingly, aortic root dilatation is now the most common cause of pure aortic regurgitation in our surgical population. The decrease in the incidence of postinflammatory disease may be a result of the decreasing incidence of acute rheumatic fever reported in western countries.

To determine long-term postoperative results in patients with double-chamber right ventricle and ventricular septal defect, 20 patients who had survived complete repair between 1959 and 1966 were recalled and studied. An interview, physical examination, electrocardiogram and chest x-ray were performed in all 20 patients, a treadmill exercise test in 16, 24-hour Holter monitor recording in 7 and postoperative cardiac catheterization in 8. Mean age at repair was 14 years and at follow-up evaluation 33 years. There were no late deaths. At a mean follow-up of 19 years, 17 patients were in New York Heart Association functional class I, 1 patient was in class II and 2 patients were in class III. Reoperation was performed in 2 patients (10%), and at present only 1 patient (5%) is considered to have hemodynamically significant cardiac compromise. Aortic regurgitation, not present in any patient preoperatively, developed in 5 patients (25%). Mild residual right ventricular outflow obstruction was present in 2 (10%) and the murmur of a hemodynamically insignificant residual ventricular septal defect or tricuspid regurgitation was present in 5 patients (25%). One patient (5%) had cardiomegaly (cardiothoracic ratio greater than 0.55). The frequency of infective endocarditis in the postoperative follow-up period was 1 per 388 patient-years. Thus, 20 years after repair of double-chamber right ventricle, mild residua and sequelae are common, but serious cardiac compromise is infrequent.

Much has been written about the changing clinical spectrum of infective endocarditis. However our survey shows that the classical text book descriptions still hold good. The majority of our patients were young with 79% either 30 years or below. Fever was present in 93%, splenomegaly in 50% and cerebral embolism in 43% of our patients. Twelve patients had valvular heart disease and 2 patients had a ventricular septal defect. Eleven out of 14 patients had a positive blood culture. Echocardiography detected definite or probable vegetations in 66% of the examinations. Five patients responded satisfactorily to antibiotic therapy, 2 patients discharged themselves from hospital against medical advice, and 4 patients underwent successful cardiac surgery. Three patients died during medical therapy.

From January 1979 to April 1983, 72 patients (pts) with bacterial endocarditis were treated. During their first stay in hospital 36 of them (age range: 23-67 years) underwent cardiac surgery because of severe congestive heart failure, unsuccessful antibiotic treatment of the infection and/or embolic events. In all these cases cardiac surgery was performed without preoperative catheterization. Surgery was recommended on the basis of clinical as well as M-mode and 2D echocardiographic findings. In 32 of the 36 pts the echocardiographic study completely predicted the surgical findings (23x the aortic valve, 1x the mitral valve, 1x the tricuspid valve, 5x the mitral and aortic valve, 1x the aortic valve and a VSD and 1x the triscuspid valve and a VSD were involved). The preoperative echocardiographic diagnosis was incomplete in 4 of the 36 pts. One aortic aneurysm, one aortic root abscess and 2x vegetations on the mitral valve were not detected by echocardiography. Surgery was recommended in these 4 pts because of additional aortic valve endocarditis proven by echocardiography. We conclude that combined M-mode and 2D echocardiography allows the accurate prediction of morphological alterations of the heart in the setting of acute bacterial endocarditis. Thus cardiac surgery can be recommended in pts with acute bacterial endocarditis without preoperative heart catheterization and coronary angiography.
