The University of Pennsylvania group, in a porcine model of ischemic mitral regurgitation (IMR), compared echocardiographic surface coaptation in two groups of pigs: Those undergoing MV repair with a flat semirigid annuloplasty ring vs. with a saddle-shaped rigid annuloplasty ring. The group found that the latter ring led to significantly improved leaflet coaptation compared to the former.
