| 目的 探讨应用实时三维超声心动图(RT-3DE)研究正常人二尖瓣环空间结构形态的价值。方法 25名正常人接受RT-3DE检查,应用Philips QLab 6.0三维软件进行分析,对瓣环进行三维重建,并计算二尖瓣环各项指标。结果 通过RT-3DE能够较精确地对二尖瓣环空间结构形态进行三维重建,并可根据三维坐标计算瓣环指标。二尖瓣环呈"马鞍形",与舒张期相比,收缩期的瓣环周长、面积、前后径、左右径、瓣环高度较小,而前后瓣环角度、左右瓣环角度较大,即收缩期二尖瓣环较舒张期更平坦。结论 RT-3DE可对二尖瓣环结构进行较精确的三维重建,可作为研究人体二尖瓣环特性的一种非介入性方法。 |

| Objective To investigate the changes of mitral annular shape during the cardiac cycle in the healthy subjects with real time three-dimensional echocardiography (RT-3DE). Methods Twenty-five healthy subjects underwent RT-3DE. The three-dimensional images were analyzed with Philips cardio-view analysis software QLab 6.0, mitral annular was reconstructed with three-dimensional structure image, and all indexes of mitral annular were calculated. Results Mitral annulus stereo configuration could be reconstructed accurately and annular parameters could be calculated with three-dimensional coordinate. The mitral annulus kept saddle shape during the cardiac cycle. The annular circumference, area, anteroposterior diameter, left-right diameter and height were smaller, but anteroposterior degree and left-right degree were larger in systole than those in diastole. Conclusion The annular stereo configuration can be three dimensional reconstructed accurately with RT-3DE, which can be used as a noninvasive method to research mitral annular dynamics in human being. |
