Surgical therapy for left ventricular aneurysms. A ten-year experience.
We reviewed retrospectively the surgical results of left ventricular aneurysm reduction in 197 consecutive patients operated on in 1977-1987. There were 19 hospital deaths (9.6%) and 38 late deaths. The cumulative 5- and 10-year survival probabilities were 79% and 67%. Of the 140 late survivors, 130 underwent follow-up study in 1988 (mean, 5 years postsurgery). We analyzed preoperative, perioperative, and postoperative variables to evaluate the efficacy of surgical therapy. The risk of early mortality was increased by worsening preoperative New York Heart Association class, operation within 30 days of myocardial infarction, combinations of ventricular arrhythmia and congestive heart failure, renal failure, and preoperative cardiogenic shock. There was a trend toward increased early mortality with multivessel coronary artery disease. Late mortality and length of survival were not predicted by any variable examined.
