    Left ventricular aneurysmectomy shows survival benefits, especially for symptomatic patients. Basilar segment function is key for prognosis, with most survivors symptom-free post-surgery.

    Area of Science:

    • Cardiology
    • Cardiac Surgery
    • Cardiovascular Research

    Background:

    • Left ventricular aneurysmectomy is a surgical procedure to address cardiac abnormalities.
    • Hemodynamic trends after surgery can be variable and difficult to predict.
    • Prognostic indicators for patient survival require further elucidation.

    Purpose of the Study:

    • To compare preoperative and postoperative hemodynamic data in patients undergoing left ventricular aneurysmectomy.
    • To identify reliable prognostic indicators for survival after left ventricular aneurysmectomy.
    • To evaluate the long-term outcomes and symptom status of patients following the procedure.

    Main Methods:

    • Retrospective analysis of 81 patients who underwent left ventricular aneurysmectomy.

  • Inclusion of preoperative and postoperative hemodynamic studies.
  • Assessment of concomitant aortocoronary bypass grafting in a subset of patients.
  • Evaluation of patient survival rates (early and late) and symptom status.

    • Main Results:

    • No consistent hemodynamic trends were observed between preoperative and postoperative states.
    • Function of the basilar ventricular segments emerged as the most reliable prognostic indicator for survival.
    • Early survival was 84%, and late survival was 71%.
    • Concomitant aortocoronary bypass grafting was performed in 62 of 81 patients.
    • Approximately 88% of surviving patients reported being essentially free of symptoms.

    Conclusions:

    • Surgical treatment for ventricular aneurysm remains a viable option for symptomatic patients.
    • Nonoperative management may be suitable for asymptomatic patients.
    • Basilar segment function is a critical factor in predicting outcomes after left ventricular aneurysmectomy.
