Abstract

Abstract The life expectancy and quality of patients with complete atrioventricular septal defect (CAVSD), which has undergone significant modifications in surgical correction since its definition, are increasing. Materials and Methods A total of 56 patients with a median age of 9 months were operated in the last 10 years. The modified single-patch (MSP) and two-patch technique (TPT) were applied to 37 patients and 19 patients, respectively. The patients were compared in terms of the ventricular septal defect (VSD) diameter, cardio pulmoner bypass (CPB) and aortic cross-clamp (ACC) time, intubation time, length of intensive care unit (ICU) in addition to demographic and hospital data. Long term results of 45 patients have been evaluated for 73,2 ± 4,06 months meanly. Results It was observed that the age distribution of the patients who underwent MSP was lower (p=0.003), and were more female patients (p=0.023). The VSD diameter was larger in the TPT (p=0.000). The right atrioventricular valve (RAVV) repair was observed significantly more in the MSP technique (p=0.043). CPB and ACC time were found to be significantly longer in the TPT technique according to the T-test result. While postoperative LAVV regurgitation was found to be lower in the MSP (p=0.016), the amount of drainage was higher in the TPT. No statistical significance was detected in other comparative values of early and the long term results of the both tecniques. Conclusion In this retrospective study, it was observed that the MSP was advantageous in surgical outcomes, its easier applicability in accordance with the literature.
