and Results— In 104 patients with idiopathic dilated cardiomyopathy who underwent annuloplasty for functional MR, basal mitral anterior leaflet angle, distal mitral anterior leaflet angle, posterior leaflet angle, coaptation depth, tenting area, mitral annular dimensions, left ventricular volumes, and MR severity were quantified by echocardiography before surgery and at 6-month intervals after it.

方法和结果：104名存在功能性MR的原发性扩张性心肌病患者接受了成形术。术前采用超声心动图检查获取基线二尖瓣前叶夹角、二尖瓣前叶远端夹角、二尖瓣后叶夹角、接合深度、幕状区面积、二尖瓣瓣环大小、左室流量以及MR程度，术后6个月复查。

Results The detecting rates of the displacement of the mitral coaptation point ,the flail partial mitral leaflets,the coarse and erratic flutter of flail leaflets, the flicking mitral chordae tendineae with coarse and erratic flutter and the vegetation by TEE and TTE with 2-D were 100%and 94.3%, 100%and 65.7%, 85.7%and 54.3%, 77.1%and48.6%, 100%and33.3%, respectively.With color Doppler imaging,eccentric wall jets or eccentric-centric jets were all detected by TEE and TTE, respectively. The regurgitant volume based on PISA method by TEE and TTE was(2025±402)and (607±268)ml/min,respectively.

结果 TEE和TTE对二尖瓣腱索部分断裂的切面超声征象包括收缩期瓣缘对合不良、局部链枷运动、局部粗大扑动、腱索断端飞鞭运动伴粗大扑动及赘生物的检出率分别为100%和94.3%、 100%和65.7%、 85.7%和54.3%、 77.1%和48.6%及100%和33.3%； TEE和TTE二尖瓣腱索断裂的彩色多普勒表现为偏心附壁返流束或偏心伴向心返流束，其检出率均为100%；根据PISA法由TEE及TTE估测的返流量分别为(2025±402)及(607±268)ml/min。

At 2years after OPBPV,right ventricular end-diastolic volume and end-systolic volume were still significantly bigger than control group (P ＜0.01) in all patients but right ventricular ejection fraction was normal,RVEDV dilatant rate correlated very well with DB/Dp ratio significantly.

RVEDV较未手术组的扩大率与球/瓣比间有非常显著相关(P＜0.01)，RVESD扩大率与球/瓣比间有相关趋势，但球/瓣比与术后即时、3月、＞2年的ΔP↓率间无显著相关(P＞0.05)。
