Surgical treatment for ischemic mitral valve regurgitation
Abstract：Objective The purpose of this paper is to review the single center's surgical experience in treatment of ischemic mitral regurgitation.Methods Retrospective analysis of 279 patients with ischemic mitral regurgitation.The mean age was (59.2±7.4)years.Heart function class 1Ⅱ 141 cases,class Ⅲ 117 cases,class Ⅳ 21 cases.Left ventricular end diastolic diameter 57-91 mm,left ventricular ejection fraction 20％-59％.The severity of mitral regurgitation:moderate in 156 cases,moderate to sever in 75 cases,48 cases were severe.The results of coronary angiography:three-vessel lesions in 240 cases,30 cases with two vessel lesions,9 patients with single vessel disease.Results Mitral valve repair in 224 cases,and postoperatively immediate TEE examination revealed no regurgitation in 152 cases,trace in 43 cases,21 cases of trace to mild and 8 cases of mild.Mitral valve replacement was performed in 55 cases.IABP assisted in 37 cases.The mean number of distal anastomosis was 3.6±0.5.13 cases died and the mortality rate was 4.7％(13/279).The left ventricular end diastolic diameter was 46-86 mm,and left ventricular ejection fraction 20％-62％ at discharge.232 cases without regurgitation,trace in 26 cases,12 cases of mild,mild to moderate in 7 cases and moderate in 2 cases.Conclusion Surgical treatment for ischemic mitral regurgitation could obtain satisfactory outcomes with greater benefit especially for the patients with reduced ejection fraction,left heart enlargement,or heart failure.
