[The surgical treatment of multiple myomas of the left heart].

5 patients with multiple left heart myxomas have been followed for 30 years. There were 4 females and 1 male at the age of 20-50 years. Two-dimensional echocardiography was used for the proper diagnosis in all cases. Open-heart surgery is the only possible method of treatment in such a situation. All the patients have been successfully operated on. To prevent the recurrence the resection of myxomas with a part of interatrial septum and endocardium was performed. The trans-sternal approach is the optimal one for the surgery of myxomas.

[Cardiac myxoma recurrence with the formation of tumors in both atria].

A case of heart myxoma recurrence 1.5 years after the removal of the left atrium primary tumour is described. Recurring tumour was represented by myxoma of both atria which was removed as a single block with a part of the interventricular septum. Both primary tumour and those of the left and right atrium have the structure of benign heart myxoma. However, the presence of the infiltrative growth into the interventricular septum allows one to consider the recurrent tumour as a borderline, locally destructive one.

[Reoperations after insertion of heart valve prosthesis].

The authors analysed 167 repeated operations after heart valve prosthetics, which were conducted from 1978 to 1988. The operations were undertaken for the second time mainly in a severe contingent of patients. The reasons for the repeated operations were specific complications according to which 2 groups of patients were set apart: with dysfunction of the prosthesis of noninfectious origin and with prosthetic endocarditis. Study showed that repeated operative intervention undertaken in time reduces considerably its risk and produces a stable positive effect in most cases.

[Surgical treatment of endocarditis following heart valve prosthesis].

Experience of many years in surgical treatment of prosthetic valve endocarditis (RVE) is analyzed. Patients whose condition was serious were operated on for a second time: 91.6% had preoperative functional class IV, in half of them circulatory disorders were of stage IIB--III; 62.4% were subjected to reoperation for emergency indications. Twenty-five reoperations were performed for early PVE with 52% hospital mortality, 23 reoperations-for late term PVE with mortality of 30.4%. The most frequent cause of PVE was staphylococcal infection which showed a tendency to increase in the recent years. In early PVE the severity of the condition in the recent years. In early PVE the severity of the condition was due to sepsis and intoxication, in late-term PVE it was caused by disorders of hemodynamics which were usually induced by dysfunction of the prosthesis. The results of surgical management of PVE depended on the severity of the patient's condition before the operation, timely performance of the operation, and the efficacy of antibacterial therapy.

[Hemangioma of the heart].

A rare observation of a cardiac benign tumour haemangioma in 17-year-old male is presented. The tumour was located in the exitus aperture of the right ventricle, originated from the interventricular septum, prolapsed into the lumen and narrowed it. Successful resection of the tumour was performed.

[Mitral commissurotomy during pregnancy].

Relying on studies into the features of the gestation course, immediate and late results, instrumental investigation findings in 91 patients with mitral stenosis prior to a surgery and in the readaptive period, indications and relative contraindications for mitral commissurotomy during pregnancy were specified and supplemented. Differential strategy was also developed for delivery of such patients.

[Calcifying myxoma of the right heart with development of thromboembolic pulmonary hypertension].

Two rare cases of calcified myxomas of the right heart (multiple myxomas of the right atrium and tricuspid valve and myxoma of the right ventricle originating from the subvalvular structures) are described. Both patients were operated, tumour and the tricuspid valve were removed and valve prosthesis was made. At necropsy changes characteristic of pulmonary hypertension resulting from the recurring thromboembolism by a tumourous tissue were found in one case.
