Sub-Commissural Annuloplasty (SCAP)
SCAP consisted of one or two sub-commissural triangle plications (Figure
1), performed by X-stitches using braided Ethibon 2/0: the first one was
usually placed under the commissure between the left coronary (LC) and
non-coronary (NC) cusps, eventually completed by additional sutures
under the commissure between the NC and the right coronary (RC) cusps or
the LC and RC cusps. Thus, SCAP permits to reduce slightly the size of
the aortic annulus, to circularize an elliptic annulus or to reshape the
annulus in the horizontal plane by reducing discrepancies between
sub-commissural triangle heights.
