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.
Does Down syndrome affect the long-term results of complete atrioventricular septal defect when the defect is repaired during the first year of life?
