Mitral Annuloplasty with New Artificial Valve Ring (Physio-II Ring)

Abstract

We report our experience in performing mitral annuloplasty using Physio ring-II, a prosthetic valve ring modification of the Physio ring, which has semi-rigid double saddle shaped structures. Subjects consisted of 4 patients who underwent mitral annuloplasty using Physio ring-II. There were no incidences of operative death or postoperative complication, and the postoperative NYHA improved to Class I in all cases. Postoperative mitral valve regurgitation was trivial in 2 cases, and not observed in 2 cases. Postoperative LDH was in the normal range in all cases, and there were no cases where hemolysis was suspected. Physio ring-II, a prosthetic valve having a structure of physiological valve ring, was considered to increase the possibility for mitral annuloplasty.
