We report a 4-month-old, 3.7-kg girl with asplenia, single ventricle physiology, a common atrioventricular valve, and severe regurgitation after repair, along with moderately depressed ventricular function. She underwent supra-annular valve replacement with a 16-mm mechanical prosthesis and 18-mm expanded polytetrafluoroethylene graft, preserving the entire valve leaflets and subvalvular apparatus. Postoperative imaging showed no inflow/outflow obstruction and preserved ventricular function. She subsequently underwent a bidirectional Glenn shunt and is currently awaiting the Fontan procedure. This approach may be a valuable surgical option in similar infants with atrioventricular valve regurgitation and ventricular dysfunction.

Heart Valves
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...
