Abstract:
Objective This study reviews the 198 consecutive mitral valve operations for elderly patients(＞ 65 y) with ischemic mitral insufficiency performed at Anzhen Hospital between January 2000 and june 2016.The results for mitral valve reconstruction are compared with those for biological mitral valve replacement.Methods From January 2000 to June 2016,198 elderly patients with ischemic mitral insufficiency underwent mitral valve reconstruction (n =150) or biological mitral valve replacement(n =48).All of them coronary artery bypass gafting was performed at the same time.Preoperative clinical characteristics,procedural characteristics,major and minor complications after surgery,preoperative and postoperative left ventricular ejection fraction (LVEF) by echocardiography,and outcome (survivor or death,mitral regurgitation,NYHA degree) were assessed.Results There was no significant difference between the two groups in the rate of mortality during hospitalization and early postoperative cardiac function.The proportion of severe MR in 1,3,and 5 years after MVP were 5.1％ 、6.3％、7.7％ respectively.There was no MVR due to the recurrent moderate-to-severe reflux.There were 2 SBE but no reflux appeared after MVR.There was no significant difference in cardiac function and mortality between the two groups within 5 years.Conclusion There is no significant difference between CABG + MVP and CABG + MVR(BV) in cardiac function and mortality in the treatment of elderly patients with IMR.,There was a possibility of MR recurrence after CABG + MVP.There was no MR after CABG + MVR(BV),but the risk of SBE is higher than MVP.We can select operation mode personalized according to the type of mitral valve disease and cardiac function.
