Long-term follow-up of atrioventricular valve function in Fontan patients: effect of atrioventricular valve surgery.

Objectives: The aim of this study was to evaluate the relationship between atrioventricular valve and ventricular function in Fontan survivors, including the effect of atrioventricular valve surgery.

Methods: Analysis focused on transplant-free survival and the need for atrioventricular valve surgery in single ventricle patients after Fontan completion. Longitudinal echocardiographic examination of long-term valve and ventricular function was performed.
