MethodsThis retrospective study included 145 consecutive patients who underwent complete atrioventricular (CAVSD) repair between January 2002 and January 2012. Peri-operative data were analyzed. Ninety-two patients had a two-patch technique (group A); 53 patients had a single-patch technique (group B).ResultsMean age was 13.17±4.94months (group A) versus 5.15±1.52months (group B), (p<0.001). Mean weight was 9.87±5.53 versus 5.23±2.12kg (p<0.001). Down syndrome was present in 82 (90.2%) in group A and 48 (90.5%) in group B (p=0.315). Aortic cross-clamp times in group A was 135.3±19.6min and group B 107.7±21.4min (p<0.0001). Cardiopulmonary bypass times were shorter in group B (132.2±24.3min) than group A (159.42±31.4min) with p value <0.001. Chylothorax, post operative bleeding, ICU stay and hospital length were not significant. Reoperation for left atrioventricular valve insufficiency occurred in 5 patients (5.4%) in group A, one of them needed valve replacement and 3 patients (5.7%) in group B. Permanent pacemaker was required for postoperative heart block in 3 patients (3.3%) in group A and 2 patients (3.8%) in group B (p=0.623). Hospital mortality was seen in 6 patients (6.5%) in group A and 3 patients (5.7%) in group B (p=0.606).ConclusionsSingle-patch technique can be performed with the same results like the two patch technique with a significantly shorter aortic cross clamp and bypass time
