Abstract:
Objective To evaluate the short-term-outcome of MVP in the treatment of moderate IMR patients with CABG.Methods Data from 129 patients with moderate IMR who underwent surgical treatment in our department from June 2007 to September 2011,57 patients(44.2％) underwent CABG combined with MVP,and 72 patients(55.8％) underwent CABG.Postoperative follow-up of patients with heart function NYHA grade to evaluate the clinical status of patients,with LVESD,LVEF,LVEDD to evaluate the reverse of left ventricular remodeling;The postoperative residual mitral regurgitation and major cardiac cerebral vascular events were recorded.Results There was no significant difference between two groups in the preoperative data(P ＞ 0.05).The mortality rate was 3.9％ (5 cases),2 cases (2.8 ％) died in CABG group,3 cases (5.3 ％) died in the combined surgery group.The average follow-up was 24 months,9 cases of late death (5 in CABG group,4 in CABG + MVP group),the cumulative survival rate(P =0.645) and the major cardiovascular events(P =0.761) of the two groups were not statistically different.The degree of mitral regurgitation(P ＜ 0.01) was significantly decreased in the combined surgery group.Compared with the preoperative state,the two groups of left ventricular remodeling indicators such as LVESD,LVEF,LVEDD were significantly improved(P ＜0.05),but the difference between two groups was not significant(P ＞0.05).NYHA heart function classification was significantly improved (P ＜ 0.001).Conclusion MVP can effectively improve the reverse flow of patients with moderate IMR,but CABG combined with MVP can not bring more benefits in the reversal of left ventricular remodeling,short-term survival and cardiac function.
