  • POST-INFARCTION VENTRICULAR SEPTAL-DEFECT - AN ARGUMENT FOR EARLY OPERATION SURGERY Gaudiani, V. A., Miller, D. C., Stinson, E. B., Oyer, P. E., Reitz, B. A., MORENOCABRAL, R. J., Shumway, N. E. 1981; 89 (1): 48-55

    Abstract:

    We reviewed our experience with 43 consecutive patients who underwent operations for postinfarction ventricular septal defect to determine optimal time for operative intervention, to identify factors responsible for failure of operative treatment, and to determine long-term survival rates. Patients were referred for operation after expectant medical management had failed or after 6 weeks electively. The operative mortality rate was 42% and ranged from 90% for those who required operation within 1 day of 11% for those underwent surgery after 1 month. In a multivariate discriminant analysis of preoperative variables, we found that inferior infarction with perforation (P less than 0.02) and preoperative multisystem failure (evidenced by abnormal mental status, P less than 0.02) were the major factors correlating with high operative risk. Early operation per se did not affect operative mortality rates. Technical problems with early operation were not a source of major morbidity and mortality. Actuarial long-term survival was good, and 88.5% of survivors were alive 5 years after surgery. Because preoperative multisystem failure is often progressive, we recommend immediate operation for all patients with postinfarction ventricular septal defect unless no deterioration is present. Moreover, because of the high risk of those patients with inferior infarction and perforation, we recommended immediate surgery for this group regardless of symptomatic status.
