| 目的 采用实时三维超声心动图(RT-3DE) 探讨陈旧性心肌梗死患者二尖瓣环的几何形态变化。方法 对21例心肌梗死患者进行RT-3DE 成像,并与12 名正常人进行对照,分析其二尖瓣环的几何形态变化。结果 心肌梗死患者中,伴有显著二尖瓣反流患者的二尖瓣环显著扩张;二尖瓣环较正常对照组瓣环平坦;二尖瓣环在心动周期中的面积变化率降低。不伴有显著二尖瓣反流患者的二尖瓣环除瓣环高度显著小于正常组外,其瓣环面积、心动周期中面积变化率、周长以及瓣环直径与正常组之间无显著差别。结论 二尖瓣环的大小和形态变化是发生缺血性二尖瓣反流的重要因素。 |

| Objective Mit ral annular geomet ry was evaluated by real-time three-dimensional echocardiography (RT-3DE)in patient s with old myocardial infarction (OMI) . Methods Twenty-one patients with myocardial infarction were imaged byRT-3DE. Mit ral annular geometry change was analyzed and compared with that of 12 normal persons. Results In patientswith OMI , those patient s with significant mit ral regurgitation (MR) , mit ral annulus dilated significantly and was more flat-ter than normal cont rol group . Mit ral annular area change rate from maximum to minimum during the cardiac cycle was low-er (17 % ±3 % vs 30 % ±5 % , P < 0. 05) . There was no significant difference in patients without significant MR comparedwith normal control group except their mit ral annular height was shorter than normal cont rol group. Conclusion Changes inmit ral annular size and shape markly cont ributed to ischemic MR. |
