Outcomes of Atrioventricular Valve Operation in Patients With Fontan Circulation
Results of AV valve surgery in patients with Fontan circulation were evaluated over a 23 year period. 54 (9.3%) of patients requird AV valve surgery, mostly prior to the Fontan operation. 90% of patients were free from death or transplantation at 5 years; this fell to 81% at 10 years. Nearly 45% required AV valve reoperation. The rate of persistent AV valve regurgitation was 26% at 5 years and 33% at 10 years.
