ong-term results after surgical repair of atrioventricular septal defect

In-hospital mortality decreased from 10.2% (n = 26) in early surgical era to 1.6% (n = 4) in late surgical era (P < 0.001). Seventy-seven patients required reoperation. Freedom from reoperation was 84.4% after 25 years. The main indication for reoperation was left atrioventricular valve regurgitation (13.8%). The multivariable Cox regression analysis revealed reoperation of the left AV valve, early surgical era, patient age <3.0 months and complex AVSD to be independent risk factors for mortality. Age <3.0 months, complex AVSD and moderate/severe left AV valve regurgitation at discharge predicted reoperation.
