Abstract

Background: Postinfarction ventricular septal rupture (VSR) is an uncommon but challenging mechanical complication for surgeons. This study analyzed the impacts of rupture size on surgical outcomes in patients with VSR.

Methods: During a 15-year period, from January 2006 to December 2020, 112 patients underwent repairs of postinfarction VSR. Patient clinical data, including angiographic and echocardiographic findings, operative procedures, early morbidity and mortality, and survival time were collated. Univariable and multivariable analyses were performed to identify the risk factors of 30-day mortality.

Results: The 30-day mortality rate was 7.1% for the whole cohort. The mean survival time estimate was 147.2 months [95% confidence interval (CI): 135.6 to 158.9 months], with a 3-year survival rate of 91.2% and a 5-year survival rate of 89.0%. Multivariable analysis revealed that rupture enlargement rate is an independent risk factor of 30-day mortality. The receiver operating characteristic (ROC) curve indicated that the rupture enlargement rate could predicted the 30-day mortality with high accuracy.

Conclusions: Delayed surgery may be considered for patients who respond well to aggressive treatment. The rupture enlargement rate is an independent risk factor for postoperative 30-day morality in patients with delayed VSR repair. Furthermore, the rupture enlargement rate has good predictive value for the prognosis of VSR patients.
