摘　　要：１３０例施行经皮二尖瓣球囊扩张术（ＰＢＭＶ）治疗的风心病二尖瓣狭窄的病人中，有二尖瓣返流（ＭＲ）者５３例，其中新出现的ＭＲ为２７例，加重者７例，术后ＭＲ未改变者１５例，减轻者４例。本结果显示：超声二尖瓣形态学积分越高，术后出现较明显的ＭＲ的机率越大；二尖瓣瓣体有明显钙化不均、融合交界有钙化以及瓣下结构有明显融合和缩短者，术后易出现较严重的ＭＲ；大多数无瓣下结构明显病变，以及无双侧交界钙化的有轻到中度ＭＲ患者仍可考虑施行ＰＢＭＶ治疗。Abstract Among the 130 patients underwent percutaneous transluminal mitral valvuloplasty (PBMV) with Inoue balloon, 53 had mitral regurgitation (MR) , including 27 of post-PBMV MR,15 of unchanged MR,7 of aggravated MR, and 4 of alleviated MR. Analysis of therelationship between different types of MR and the echocardiographic mitral morphology showed that: patients with a higher basal mitral score had a higher incidence of developing severe MR following PBMV; MR especially severe MR easily developed in patients with uneven mitral leaflet calcification, marked commissural calcification and fusion, and thickening or shortening of subvalvular tissue. The above echocardiographic findings may be valuable markers for predicting MR; and PBMV can be performed in most mitral stenotic patients with mild to moderate MR if their mitral valves have no such echo findings.
