摘　　要：目的　评价经胸超声心动图(TTE)在经皮二尖瓣球囊扩张术(PBMV)的应用价值。方法　对14 5例风湿性二尖瓣狭窄患者在PBMV术前、术后通过TTE检测瓣口面积(MVA)及左心房压力(LAP)测定结果进行回顾性分析。结果　手术成功率为97.2 % (14 1/14 5 )。所有病例二尖瓣瓣口面积由术前平均(1.0 3±0 .15 )cm2 扩大至(1.79±0 .19)cm2 (P <0 .0 1) ,左心房压力由术前(2 2 .5±6 .2 )mmHg(1mmHg =0 .133kPa)降至(13.8±4 .6 )mmHg (P <0 .0 1)。结论　TTE检查对PBMV术前病例选择、术后疗效的评价具有重要意义。Objective To evaluate effectiveness of transthoracic echocardiography (TTE) for percutaneous balloon mitral valvuloplasty (PBMV) with the inoue technique. Methods The study group consisted of 145 patients with rheumatic mitral stenosis (MS) underwent TTE before and after PBMV. Mitral valve area (MVA) and left atrial pressure (LAP) were measured by TTE. Results The success rate of PBMV was 97.2%(141/145). PBMV produced a significant increase in MVA from (1.03±0.15) cm2 to (1.79±0.19) cm2 ( P<0.01),and a reduction in LAP from (22.5±6.2) mm Hg to (13.8±4.6) mm Hg (P<0.01). Conclusion TTE is very important in selecting patients before PBMV and evaluating curative effect after PBMV.
