Abstract:
Objective The preservation of all subvalvular apparatus for chronic mitral regurgitation has been reported in many studies. In this paper we analyzed the effects of complete chordal preservation for mitral stenosis versus mitral regurgitation on postoperative recovery.Methods Thirty-nine patients undergoing mitral valve replacement(MVR) with preservation of all subvalvular apparatus were divided into two groups, mitral stenosis (MS) group(n=23) and mitral incompetence (MI) group(n=16), according to the preoperative diagnosis. Echocardiography was performed preoperatively and at the time of discharge to determined left ventricular end diastole dimension (LVEDD),ejection fraction(EF) and the hemodynamics of the prosthesis.Results The LVEDD and EF did not change in MS group, declined in MI group postoperatively. No hemodynamic disorder of the prosthesis was detected in either group.Conclusions The valve replacement with preservation of all subvalvular apparatus could be used in both the mitral stenosis and mitral regurgitation.The early-term effects of two groups are similar,and the long-term effects are still to be observed.
