[Surgical treatment of heart myxomas]. / Khirurgicheskoe lechenie miksom serdtsa.

Nine persons were operated on in the Samara Interregional Cardiosurgical Center for left atrial myxoma in 1986-1991. Two-dimensional echocardiography was the major technique in making a correct diagnosis. The tumor was found in one patient intraoperatively. An operative access was made through the right atrium and atrial septum. The tumor was excised at the wide margin of the underlying myocardium. The postoperative period in all patients was smooth.

[10-year experience with correction of supraventricular tachycardia]. / Desiatiletnii opyt korrektsii nadzheludochkovykh takhiaritmii.

The results of a 10-year experience in surgical treatment of supraventricular tachyarrhythmias in 258 patients are analysed. Invasive and noninvasive methods of electrophysiological studies with the predominant use of Soviet-produced apparatuses were employed in establishing the diagnosis. Surgery of arrhythmias included catheter destruction, cryosurgery on a working heart, but the prevailing methods were various types of destruction of anomalous conducting paths under conditions of extracorporeal circulation. The authors suggest a method for dosed electrocoagulation of paranodal tissues in atrioventricular nodal tachycardias. The results of the operation were positive in over 90% of cases. Three fatal outcomes in operations with extracorporeal circulation occurred during the first years of accumulation of experience in the method. It is concluded that the operation is highly effective in severe tachyarrhythmias.
