    Abstract:
    We assessed midterm outcomes, predictors of mortality, and residual defects after repair of post-infarction ventricular septal defect in 10 patients (mean age, 65.3 years; range, 50-78 years) who were operated on between 2000 and 2008. Mean time from onset of symptoms of myocardial infarction to diagnosis of ventricular septal defect was 3.5 days. Time from diagnosis to surgery ranged from 6 h to 84 days. The defects were located anteriorly in 4 patients and posteriorly in 6. Patch reconstruction of the septum was used in 6 patients and the infarct exclusion technique in 4. Hospital mortality was 60%. The only predictor of mortality was tricuspid valve competence (p = 0.048). There was no correlation between location of the defect or type of repair and operative mortality. Residual or recurrent ventricular septal defect was noted in 6 patients. Location of the defect and type of repair were not predictors of residual or recurrent defects. Residual ventricular septal defect was not associated with increased short-term mortality or reduction of functional status. Early mortality associated with post-infarction ventricular septal defect repair is significant. Discharged patients continue to have good functional capacity and quality of life, as well as favorable midterm survival.
