Ventricular tachycardias occurring after myocardial infarction (MI) and resistant to medical treatment were successfully treated in 5 patients by encircling endocardial ventriculotomy. All patients had a history of MI. The delay between MI and ventricular tachycardias ranged from 1 month to 8 years. A reentrant mechanism was demonstrated by laboratory studies. Under cardiopulmonary bypass, the left ventricle was entered through the thin fribrous scar. Encircling endocardial ventriculotomy was carried out from the inside of the ventricle, through the whole thickness of the normal myocardium, and along the border of the endocardial fibrosis, which delineated the area of diseased myocardium. The ventriculotomy was placed in the free wall or in the septum or in both of these locations. It was repaired and the left ventricle was closed. Drug therapy was discontinued after operation. No ventricular tachycardias recurred during a follow-up period of 6 to 24 months. The effectiveness of encircling endocardial ventriculotomy is explained by the exclusion of the entire diseased area, especially the border zone and the septum. This technique is useful in any location of MI.
