SURGICAL TREATMENT FOR MALIGNANT VENTRICULAR TACHYCARDIA FOLLOWING MYOCARDIAL INFARCTION RESISTANT TO MEDICAL TREATMENT

Twelve patients with malignant ventricular tachycardia (VT) occurred following myocardial infarction were operated and their clinical pictures, pre and intraoperative electrophysiological studies (EPS) and operative results were reported. This type of VTs was most frequently observed with the aneurysm of large size as well as poor cardiac function. Intraoperative mapping in eleven of twelve patients was performed and sustained VTs were successfully induced in nine. The findings on the localization of the focus in the epicardial and endocardial mapping were coincident with the VT originated from the free wall, however in the VT originated from the septum, the real focus was observed at the point slightly distant from the break-through by epicardial mapping. A recurrence was observed in one patient in whom the origin of focus could not be detected, therefore, it appears to be mandatory to confirm the real focus by doing endocardial mapping especially in those VTs originated from the septum. For the ablation of VT, the endocardial excision and cryosurgery were successfully undertaken which also showed to give few influence for the deterioration on the cardiac function.
