title: [Subendocardial resection in the surgical treatment of ventricular arrhythmia in patients with ischemic heart disease].
abstract: Since 1977 a total of 284 operations were conducted on patients with ventricular tachycardia consequent upon ischemic heart disease. Stimulation mapping was used during the operation as an auxiliary method for locating the arrhythmogenic zone in the ventricles. Demonstration of low-voltage and fragmented activity (delayed potentials) in the sinus rhythm are of diagnostic value in no more than 30% of cases. The results of endocardial preoperative mapping are very important because in 99% of cases the focus of ventricular tachycardia is located endocardially (in the septum of the heart in 2/3 of cases). Dosed endocardial resection is the operation of choice; when the focus is located intramyocardially (or in the region of the base of the papillary muscle) the authors resort to cryodestruction. Operative mortality was 15%. The operations were successful in follow-up periods of up to 10 years in 70% of cases.
