Abstract:
Patients with common atrioventricular valve( CAVV) regurgitation are at increased risk of mortality and adverse outcomes during single ventricle palliation. CAVV repair is one of the most challenging techniques in pediatric cardiac surgery. Especially in patients who require CAVV repair before Glenn operation have the complicated valve anatomy and sometimes need repeat valve surgery. Several techniques of CAVV repair include annuloplasty, commissuroplasty, cleft closure, edge-to-edge repair, and bivalvation. Prosthetic valve replacement for uncontrollable CAVV regurgitation in patients with single ventricular physiology is the last available option entailing a moderately high risk of death, valve dysfunction, and redo valve replacement.
