【摘要】：目的应用实时三维经食管超声(RT-3DTEE)分析二尖瓣脱垂患者二尖瓣瓣环立体结构在全心动周期的动态变化特征。方法 57例行RT-3DTEE检查,对照组33例,二尖瓣脱垂患者(MVP组)24例。应用二尖瓣定量分析软件于舒张早、中、晚期(ED,MD,LD),收缩早、中、晚期(ES,MS,LS)测量二尖瓣瓣环。结果 (1)MVP组DAP于ED最大,DAlPm至LD最大,逐渐减小至ES,H于LD至LS升高,H/DAlPm至MS最大,E2D至ES最大。(2)与舒张期相比,MVP组DAP于MS明显减低,H、H/DAIPm于LS明显增大,E2D于MS明显增大(P0.05),而DAlPm各期间比较差异均无统计学意义(P0.05)。结论 MVP瓣环是动态变化的,收缩期仍保留"马鞍形"结构,但运动幅度增大。
[Abstract]:The purpose of real-time three-dimensional transesophageal echocardiography (RT-3DTEE) in patients with mitral valve prolapse of mitral valve ring analysis of three-dimensional structures in dynamic characteristics of the whole cardiac cycle. Methods RT-3DTEE was performed in 57 cases, 33 cases in the control group, patients with mitral valve prolapse (MVP group) 24 cases. The software in early diastole, mitral valve quantitative analysis application in advanced (ED, MD, LD), systolic, early and late (ES, MS, LS) measurement of mitral annulus. Results (1) MVP group DAP in ED, DAlPm to LD, decreased to ES, H from LD to LS increased, H/DAlPm to MS, E2D to ES (2). Compared with MVP group DAP in diastole, MS decreased significantly, H, H/DAIPm in LS increased significantly, E2D increased significantly in MS (P0.05), while there were no significant differences in the comparison of the DAlPm period (P0.05). Conclusion MVP annulus is dynamic, systolic still retains a "saddle shape" structure, but the range of motion increased.
