title: Surgical repair of partial atrioventricular defect.
abstract: Long-term survival rate of patients operated for partial atrioventricular (AV) canal is lower than that of the general population, and late complications are relatively significant: between 10 and 30% of operated patients present with left AV valve regurgitation, and up to 25% have to be reoperated for valve repair or replacement, left ventricular outflow tract obstruction or residual atrial septal defect. Because the left AV valve regurgitation is the most common complication following surgery, technical details in the surgical management of the mitral valve are the most important aspects of this procedure; for example, the decision to close the cleft and to perform an annuloplasty. The presence of mitral valve anomalies in 7-28% of the cases complicates further the surgical management of these valves. This article will describe in detail the operative technique of partial AV canal repair, and review the relevant literature.
