Postinfarction ventricular septal defect: an argument for early operation

V A Gaudiani, D G Miller, E B Stinson

    Surgery
    |January 1, 1981
    PubMed
    Summary

    Immediate surgery for postinfarction ventricular septal defects is recommended, especially for those with inferior infarction and perforation. Early intervention does not increase operative mortality, and long-term survival is favorable.

    Area of Science:

    • Cardiology
    • Cardiac Surgery
    • Cardiovascular Research

    Background:

    • Postinfarction ventricular septal defect (VSD) is a severe complication of myocardial infarction.
    • Optimal timing for surgical intervention remains a critical consideration.

    Purpose of the Study:

    • To determine the optimal timing for surgical intervention in postinfarction VSD.
    • To identify factors associated with operative treatment failure.
    • To assess long-term survival rates after surgical repair.

    Main Methods:

    • Retrospective review of 43 consecutive patients undergoing surgery for postinfarction VSD.
    • Analysis of preoperative variables using multivariate discriminant analysis.
    • Evaluation of operative mortality and long-term survival rates.

    Main Results:

    • Overall operative mortality was 42%, with higher rates for early operations (90% within 1 day) versus later operations (11% after 1 month).
    • Inferior infarction with perforation and preoperative multisystem failure (abnormal mental status) were significant predictors of high operative risk.
    • Actuarial long-term survival was good, with 88.5% of survivors alive at 5 years post-surgery.

    Conclusions:

    • Immediate surgical intervention is recommended for postinfarction VSD, particularly in cases with inferior infarction and perforation, or progressive multisystem failure.
    • Early operation itself did not increase operative mortality; technical issues were not major contributors to morbidity or mortality.
    • Favorable long-term survival supports aggressive surgical management in selected patients.
