Outcomes of atrioventricular valve operation in patients with fontan circulation

Abstract

Background Data on outcomes of atrioventricular (AV) valve surgical procedures in patients with Fontan circulation are limited. Methods We conducted a retrospective review of all children with Fontan circulation who underwent AV valve operations. Results From 1981 to 2014, 581 patients underwent Fontan operations, and 9.3% (54/581) of them required AV valve operations. The first AV valve operation was performed before (n = 32), during (n = 15), or after (n = 7) the Fontan operation. The mean follow-up time was 9.8 ± 7.1 years (range, 6 months to 32 years). Operative mortality for the initial AV valve operation was 1.9% (1/54) and occurred in a patient who had the initial valve operation conc..
