Repair of common atrio-ventricular valve in univentricular circulation using adjustable annular bridging technique

The main reason for common atrioventricular valve (CAVV) regurgitation is the enlargement of the valve annulus contralaterally to the aorta and pulmonary artery. Edge-to-edge (ETE) repair can be used to address the regurgitation; however, there might be potential disadvantage that a fixed bridging leaflet could have a restrictive motion, leading to recurrence of AVV regurgitation. To avoid this issue and address the anteroposterior dilatation of the annulus, we have developed an adjustable annular bridging technique.
