Bivalvation with bridging for common atrioventricular valve regurgitation in right isomerism

Current options and outcomes for the management of atrioventricular septal defect

“…One technique has been by incising both anterior and posterior bridging leaflets and joining the free edge of the ventricular patch at a right angle to the base of the left AV valve [42]. In newborns and young infants additional valvar support has been achieved using a small Gortex tube parallel to the VSD placed across the bridging valve leaflets [43]. Our preference remains to avoid left AV valve replacement using prosthetic valves in young children wherever possible, even if this entails multiple operations over a period of years to achieve satisfactory left AV valve performance.…”

Contemporary management of right atrial isomerism: Effect of evolving therapeutic strategies

“…Those with balanced ventricles might present a challenge for biventricular repair because of a combined AVSD [20][21][22][23][24][25][26] and conotruncal anomaly. 1,27 Clinical reports of biventricular repair for RAI have been rare and sporadic.…”

Outcomes of Common Atrioventricular Valve Repair in Patients With Single-Ventricle Physiology ― Indication, Timing and Repair Techniques ―

“…3,12,16,17 We prefer the bivalvation technique, which was derived from the edge-toedge technique in the early 1990s, 18 and was first introduced as a CAVV repair technique in the mid-1990s. 19 Compared with the modified Alfieri technique 17 and two-strip technique, 20 in our bivalvation technique only one Gore-Tex strip is used on the atrial side to shorten the anteroposterior diameter without any sutures on the leaflet, and a similar technique was introduced by Sughimoto et al in 2015. 21 Considering the fragility of the dysplastic leaflet, 15 5 layers of leaflet and fresh pericardium structure were adopted by us.…”
