Abstract
This study determined predictors of operative survival and improved long-term outcomes in patients undergoing ventricular aneurysmectomy. Since the first successful repair of ventricular aneurysm in 1958, refined technique and improvement in perioperative care have been introduced to lower morbidity and mortality. The authors reviewed their institutional experience from 1968 through 1993 in treating 523 patients who underwent ventricular aneurysmectomy. Overall operative mortality was 8% and overall median survival was 128 months. Contractility grade, age, and year of operation were predictors of operative mortality and of improved long-term survival. Type of aneurysm repair was not a strong predictor of operative mortality or improved long-term survival. Ventricular aneurysmectomy can be performed safely using one of a number of established techniques, although operative mortality and long-term survival may not depend on the techniques used.
