Objective To attempt an innovative mitral valvuloplasty by chained double stitching without shaping ring to repair ischemic mitral regurgitation (IMR) and to evaluate the clinical efficacy of this new procedure. Methods We retrospectively analyzed the clinical data of 12 patients with coronary artery disease and IMR underwent the innovative mitral valvuloplasty by chained double stitching without shaping ring in our hospital from August 2012 to December 2013. There were 10 males and 2 females at the mean age of 60±10 years ranging from 42 to 76 years. The cardiac functional parameters and condition of mitral regurgitation were compared among the period of preoperation, discharging and follow-up. Results Twelve patients were recovered and discharged from hospital with the New York Heart Association (NYHA) classification of heart function at class Ⅰ-Ⅱ. NYHA classification, grade of mitral regurgitation and regurgita- tion area were statistically improved on both the phase of discharge and follow-up compared with that of the pre-operation (P<0.05). Compared with preoperative left ventricular ejection fraction (LVEF), LVEF of discharging was statistically amelio- rative (P<0.05). And there was a statistic difference of NYHA classification of cardiac function in the phase of follow-up than that of discharging (P<0.05). Conclusion Mitral valvuloplasty by chained double stitching without shaping ring is one reliable choice of treating IMR. The cardiac function and the living quality of the patients are statistically improved on the early stage and metaphase after operation, but long-term efficacy of this surgical procedure need be further assessed.
