[Surgical treatment of primary tumors of the heart].

The article discusses the experience in surgical treatment of tumors of the heart in 34 patients in clinics of cardiosurgery at the Riga Medical Institute and the Institute of Cardiology and Cardiovascular Surgery of Havana (Cuba). Twenty-five patients underwent operations for benign tumors of the heart (16 myxomas, 2 leiomyomas, 2 fibromas, 1 lipoma, 1 angiofibroma, 2 coelomic cysts) under extracorporeal circulation, with 4% lethality. No recurrences were encountered in follow-up periods of 5 months to 14 years. Nine patients had malignant tumors; the tumor was removed successfully in 3 of them, even with resection and prosthetic replacement of the outflow tract of the right ventricle. Only 3 of the patients (33%) who were operated on had a follow-up period of more than 1 year.
