Key result
Left ventricular aneurysmectomy in 81 patients yielded 84% early and 71% late survival, with 88% of survivors symptom-free, supporting surgical treatment for symptomatic patients.

What are the outcomes and prognostic indicators for survival in patients undergoing left ventricular aneurysmectomy?
Left ventricular aneurysmectomy provides good survival and symptom relief, supporting surgical treatment for symptomatic patients and nonoperative treatment for asymptomatic patients.
May support aneurysmectomy for symptomatic relief; leaves open need for randomized confirmation of survival benefit.
Comparison of preoperative and postoperative studies in 81 patients undergoing left ventricular aneurysmectomy failed to show consistent hemodynamic trends. The most reliable prognostic indicator for survival (84% early, 71% late) was the function of the basilar ventricular segments. In 62 of the 81 patients, there was concomitant aortocoronary bypass grafting. Eighty-eight percent of the surviving patients are essentially free of symptoms. These findings support the continued surgical treatment of ventricular aneurysm in symptomatic patients, and suggest nonoperative treatment for patients who are asymptomatic.

Joseph D. Marco (1976) conducted an observational in Left ventricular aneurysm (n=81). Left ventricular aneurysmectomy was evaluated on Hemodynamic trends and survival. Left ventricular aneurysmectomy in 81 patients yielded 84% early and 71% late survival, with 88% of survivors symptom-free, supporting surgical treatment for symptomatic patients.
