A new method for atrioventricular valve repair in atrioventricular septal defect

This may be complicated with stretching/dehiscence of the sutured zone by naturally-diverging cordal traction, and stenosis by restricting leaflet mobility. This prompted us to develop a different approach, especially for adults and adolescents, who may or may not have undergone surgical repair previously. It consists in not closing/re-opening the “cleft”, constructing neo-cordae connecting the cordless edge of each bridging leaflet to the opposite papillary muscle, i.e. the papillary muscle to which it has no natural connection (“crossing neo-cordae”), and inserting an annuloplasty ring.
