Abstract

•Percutaneous repair of severely regurgitant atrioventricular valves in the setting of a Fontan circulation utilizing Tri-Clip, even in the setting of an atrioventricular septal defect, is feasible.•Percutaneous options hold promise as a low-risk repair strategy in this highly complex population, which generally has a high surgical risk.
