Ring dehiscence is a serious complication after mitral valve annuloplasty, tending
to occur primarily from the posterior annulus. The tension on the ring sutures during
the cardiac cycle is one of the suspected reasons; to minimize this tension, we apply
four additional pledgeted sutures positioned supra-annularly at critical hinge points
and could achieve a marked reduction of annular dehiscence since.
