    Emergency surgery for left ventricular asynergy after myocardial infarction showed high mortality. Prompt intervention, especially within three months, yielded poorer outcomes in this patient cohort.

    Area of Science:

    • Cardiology
    • Cardiac Surgery
    • Cardiovascular Research

    Background:

    • Left ventricular asynergy is a serious complication post-myocardial infarction.
    • Surgical intervention is considered for severe cases.
    • Limited data exists on outcomes of emergency surgical repair.

    Purpose of the Study:

    • To analyze the indications and outcomes of emergency surgical procedures for left ventricular asynergy.
    • To evaluate the impact of timing on post-operative mortality.

    Main Methods:

    • Retrospective analysis of 32 patients undergoing emergency surgery for left ventricular asynergy.
    • Procedures included aneurysmectomy or plication, often combined with valve replacement, septal defect closure, or bypass grafting.
    • All surgeries utilized cardiopulmonary bypass.

    Main Results:

    • Overall early post-operative mortality was 75%.
    • Mortality was higher (80%) in patients operated within three months of myocardial infarction.
    • Mortality was lower (67%) in patients operated after three months.

    Conclusions:

    • Emergency surgical repair of left ventricular asynergy carries a high early mortality risk.
    • Operating beyond three months post-myocardial infarction may be associated with improved survival rates.
    • Further research is needed to optimize surgical timing and patient selection.
