[Efficacy of the surgical treatment for malignant heart tumors].

Peculiarities of malignant cardiac tumors surgical treatment were studied, basing on analysis of 33 observations. Rhabdomyosarcoma was diagnosed in 9 patients, angiosarcoma--in 11, leyomyosarcoma--in 6, malignant mixoma--in 4, fibrosarcoma, chondrosarcoma and liposarcoma--each as a single observation. Special attention was paid to guarantee the maximal radicalism in the tumor excision, what made it necessary in 8 observations to perform additive surgical procedures, such as interatrial septum and atrial walls plasty, plastic operations on cardiac valves and the valves prostheses. The operation volume extension did not influence significantly its immediate result.
