Modified single-patch technique for children with complete atrioventricular septal defect in a single center / 中国胸心血管外科临床杂志

ABSTRACT

@#Objective    To sum up the experience of the primary modified single-patch (MSP) technique applied in our hospital for children with complete atrioventricular septal defect (CAVSD). Methods    The 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. Results    Postoperatively, 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. Conclusion    MSP technique is a wise surgical strategy for CAVSD children with good outcomes, improved postoperative mortality and decreased atrioventricular valve regurgitation.
