We present our clinical experience with 37 @entity1 presenting with @entity1165 who, between 1980 and 1986, underwent subendocardial resection, guided by per-operative mapping in 34 cases. An @entity439 of the left ventricle was present in 23 @entity1 (62%), and an @entity2845 area in the remaining 14 @entity1 . In every case the cause of @entity1165 was an @entity299 . Prior to surgery, the global isotopic ejection fraction was 27 +/- 11% and the left ventricular end-diastolic pressure was 21 +/- 8 mmHg. The most common site of origin of the @entity943 was the septum (26 cases, 77%). The mean area of resection was 26 +/- 16 cm2. Resection of a @entity439 was also performed in 23 cases, and 22 @entity1 underwent coronary bypass. There were 4 early @entity204 (operative mortality rate : 10.8%) and 4 late @entity204 . The actuarial survival rate was 89 +/- 5% at 6 months and 72 +/- 9% at 24 months. One-half of the @entity204 was due to recurrence of the @entity1165 . A post-operative electrophysiological study conducted in 30 @entity1 proved negative in 28 (93%). Altogether, there were 6 immediate or late failures (16.2%) after a mean follow-up period of 18 months. The probability of a relapse-free, medication-free life or @entity944 was 86 +/- 6% after 6 months and 82 +/- 7% after 24 months. The quality of life of the survivors war remarkable, since 86% of them (25/29 @entity1 ) remained in functional class 1 or 2 after surgery.(ABSTRACT TRUNCATED AT 250 WORDS)
