Long-term outcomes after atrioventricular valve operations in patients undergoing single-ventricle palliation

Abstract

Background: Outcomes after atrioventricular (AV) valve operations in patients with functional single ventricles are unclear. Methods: From 1988 to 2010, 76 consecutive patients with single ventricles underwent AV valve operations for regurgitation at a single institution. Five replacements, 66 repairs, and 5 valve closures were performed at a median age of 1 year (range, 1 day-14 years) on 43 tricuspid, 9 mitral, and 24 common AV valves. Results: Hospital mortality was 17% (13/76). The follow-up was 100% complete. There were 15 late deaths. There were 48 survivors with a mean follow-up of 8.3 ± 6 years. One- and 10-year Kaplan-Meier survival after AV valve operations was 72% (95% confidence ..
