[Ventricular tachycardia of ischemic origin. Surgical treatment by encircling thermo-exclusion using the Nd-Yag laser].

Abstract

Refractory and recurrent ventricular tachycardias are a common cause of death after myocardial infarction. The occurrence of intraventricular re-entries can be prevented by a new surgical treatment based on encircling thermic exclusion. The Nd-YAG laser beam offers 2 major advantages over previous techniques: it acts rapidly with minimal myocardial damage and can even be used in patients with left ventricular dysfunction.
