    Surgical resection of left ventricular aneurysms can improve outcomes. Long-term survival depends on remaining heart muscle function, with combined bypass grafting potentially enhancing prognosis in multivessel disease patients.

    Area of Science:

    • Cardiovascular Surgery
    • Cardiac Surgery
    • Interventional Cardiology

    Background:

    • Left ventricular aneurysms often coexist with coronary artery disease.
    • Surgical intervention aims to resect aneurysms and revascularize coronary arteries.
    • Patient selection and surgical strategy are crucial for optimal outcomes.

    Purpose of the Study:

    • To evaluate operative and long-term outcomes of left ventricular aneurysm resection.
    • To identify predictors of survival after aneurysmectomy.
    • To assess the impact of concomitant coronary artery bypass grafting.

    Main Methods:

    • Retrospective analysis of 55 patients undergoing left ventricular aneurysm resection.
    • Assessment of preoperative factors influencing survival.

  • Evaluation of the role of simultaneous aorto-coronary bypass grafting.
  • Main Results:

    • Age >60, severe heart failure, and low cardiac output predicted decreased survival.
    • The functional state of residual myocardium was the primary determinant of long-term survival.
    • Concomitant bypass grafting did not show a statistically significant advantage in this series but is suggested for multivessel disease.

    Conclusions:

    • Left ventricular aneurysmectomy is feasible with acceptable outcomes.
    • Myocardial function post-resection is key to long-term survival.
    • Combining bypass grafting with aneurysmectomy may improve prognosis in patients with multivessel coronary artery disease.
