Background: The spectrum of atrioventricular septal defects account for about 7-17% of congenital heart disease, and 25% of them are partial atrioventricular canal defects (2). The repair of partial atrioventricular canal are preferred to be performed when diagnosed and before an operation might interfere with school. According to the long-term follow-up results of other centers, surgical outcomes were excellent. There were many reports about the surgery outcomes of patients in young age. The aim of this retrospective study is to review the results of treating infants with partial atrioventricular canal patients in our center. The mortality rate, reoperation rate, surgery procedures and valve regurgitation associated data were described.
