Summary

Predictors of survival after postinfarction ventricular septal defect (VSD) repair were identified. Preoperative cardiogenic shock and early septal rupture indicate a poor prognosis, while timely surgery improves outcomes.

Area of Science:

  • Cardiovascular Surgery
  • Cardiac Surgery Outcomes
  • Mechanical Circulatory Support

Background:

  • Postinfarction ventricular septal defect (VSD) is a severe complication of myocardial infarction.
  • Surgical repair of postinfarction VSD is complex with significant early and late mortality.
  • Identifying predictors of outcome is crucial for patient management.

Purpose of the Study:

  • To identify predictors of early and late outcomes in patients undergoing surgical repair of postinfarction VSD.
  • To analyze the impact of various clinical factors on survival and functional status.

Main Methods:

  • Retrospective analysis of 117 consecutive patients who underwent VSD repair over 12 years.
  • Multivariate analysis using logistic regression and Cox regression.

  • Evaluation of factors including age, sex, VSD location, cardiogenic shock, time to surgery, and use of intraaortic balloon pump (IABP).

    • Main Results:

    • Thirty-day mortality was 37%. Preoperative cardiogenic shock (OR 5.7) and hemodynamic deterioration (OR 6.0) were significant predictors of early mortality.
    • A longer interval between myocardial infarction (MI) and surgery favored survival (OR 0.1).
    • Five-year survival was 46%. Preoperative cardiogenic shock adversely affected late survival (OR 2.7).

    Conclusions:

    • Preoperative cardiogenic shock and early postinfarction septal rupture are associated with a grave prognosis.
    • Achieving hemodynamic stability before surgery may be beneficial, but prolonged attempts can be hazardous.
    • Timely surgical intervention after myocardial infarction and VSD development appears to improve survival.
