Objective To compare the postoperative outcomes of modified single-patch technique and one-and-a-half-patch technique for complete atrioventricular septal defect (CAVSD) with a large ventricular component (>1 cm). Methods We retrospectively reviewed clinical data of 79 CAVSD patients with a large ventricular component (>1 cm) in Shanghai Children's Medical Center from January 2005 through January 2016. There were 37 males, 42 females with a median age of 8 months (range, 1.5 months to 10.2 years). Among the patients, 45 patients (20 males, 25 females) with a median age of 6 months(range, 1.5 months to 10.2 years) received modified single patch technique and 34 patients (17 males, 17 females) with a median age of 5.3 months (range, 2.5 months to 8.3 years) underwent one-and-a-half-patch (1.5-patch) technique. All the patients complicated with complex malformation such as double outlet of right ventricular, single ventricle, and transposition of great arteries were excluded. Results The mortality and reoperation rate in modified single-patch group were higher than those of the one-and-a-half-patch group. There were 2 postoperative early deaths in the modified single-patch group (4.4%). Among them, one patient died of postoperative valvular regurgitation and heart pump failure. The other one died of respiratory failure caused by severe pneumonia. There were 3 reoperations. Two patients performed valve plastic surgery because of valve regurgitation and one patient because of residual ventricular septal defect. There was no death and reoperation in the one-and-a-half-patch technique group. No left ventricular outflow tract obstruction and atrioventricular block in both groups were developed. Conclusion The 1.5-patch technique is an attractive clinical option in CAVSD patients with a large ventricular component.
ObjectiveTo sum up the experience of the primary modified single-patch (MSP) technique applied in our hospital for children with complete atrioventricular septal defect (CAVSD).MethodsThe clinical data of 141 children who underwent primary MSP technique for CAVSD between June 2009 and December 2017 were retrospectively analyzed, including 62 males and 79 females with a median age of 6 (3, 11) months and a median weight of 5.8 (4.5, 7.0) kg. According to Rastelli classification, there were 116 patients in type A, 14 in type B and 11 in type C. Among them, 15 patients were diagnosed with Down’s syndrome. Cardiopulmonary bypass time, aortic cross clamp time, atrioventricular valve regurgitation and other clinical data were recorded during and after operation. ResultsPostoperatively, 17 patients suffered from severe left atrioventricular valve regurgitation (LAVVR) and 6 patients severe right atrioventricular valve regurgitation (RAVVR). In the follow-up period, 5 patients suffered from severe LAVVR and 1 patient severe RAVVR. Left ventricular outflow tract obstruction (LVOTO) appeared in 1 patient during follow-up period and none at the end of follow-up. There were 5 early deaths and 2 late deaths. Twelve patients underwent reoperation with a median interval time of 268 (8, 1 270) days.ConclusionMSP technique is a wise surgical strategy for CAVSD children with good outcomes, improved postoperative mortality and decreased atrioventricular valve regurgitation.
