Popis: Postmyocardial infarction intraventricular septal rupture is a life-threatening medical condition. Surgical management of postmyocardial infarction ventricular septal defects (PIVSDs) is associated with a 60% mortality and a 40% incidence of residual ventricular septal defects (rVSDs). Our study aimed to describe our modification of the "Double-patch" technique of PIVSD repair without using a biological glue and present its postoperative complications and survival.This was a retrospective observational study. The Bakoulev's Scientific Center of Cardiac Surgery patient admission and discharge database was reviewed from March 2002 to April 2021. The inclusion criterion was PIVSD. Exclusion criteria were conservative treatment, transcatheter closure of PIVSD, PIVSD closure with an interventricular septum patch, and chronic PIVSDs. The study outcomes were echocardiographic parameters of cardiac function, postoperative complications, and mortality.Forty nine patients met the study eligibility criteria. Comparison of echocardiographic data of cardiac function demonstrated reduction in the postoperative period end-diastolic (201.4 ± 59.6 ml vs. 118 [range: 76-207] ml; p .0005) and end-systolic volumes (106 [51-208] ml vs. 66 [40-147] ml; p .0005). One (2%) patient developed hemodynamically significant rVSD that required the second run of cardiopulmonary bypass and rVSD closure. Thirteen (26.5%) patients died in the hospital. The overall mortality rate for the study period was 11.4/100 person-years (95% confidence interval [CI]: 6.9-19.0/100 person-years). In these patients, 1-year survival was 68.2% (95% CI: 52.3%-79.8%) and 5-year survival was 63.1% (95% CI: 45.1%-76.7%).The "Double-patch frame" technique restores LV dimensions, has a low rate of hemodynamically significant rVSDs and mortality.
