【摘要】：目的采用经食管实时三维超声心动图(RT 3D-TEE)重建二尖瓣解剖结构,探讨二尖瓣环、瓣叶各参数随心动周期的变化规律。方法 18例阵发性房颤患者行RT 3D-TEE检查,于左室长轴观采集3个心动周期包含完整二尖瓣环及瓣叶的三维超声图像。运用eSie Valves分析软件获得二尖瓣环及瓣叶各参数的动态值。结果二尖瓣环面积、周长、前后径、连合间径、非平面角度、主动脉瓣环与二尖瓣环间夹角测值收缩期舒张期(P0.05),而瓣环高度、瓣环高度/连合间径测值收缩期舒张期(P0.05);前瓣叶总面积及A1、A2、A3区面积和长度收缩期舒张期(P0.05),后瓣叶总面积及P1、P2、P3区面积和长度在收缩期和舒张期间的差异无统计学意义(P0.05)。二尖瓣各参数组内及组间测值的一致性分析显示一致性好。结论 RT 3D-TEE能快速定量分析二尖瓣环及瓣叶各参数随心动周期的变化规律,且一致性好,可为二尖瓣的修复、置换手术提供参考。
[Abstract]:Objective to reconstruct the anatomical structure of mitral valve by transesophageal real-time three-dimensional echocardiography (RT3D-TEE) and to investigate the changes of mitral annulus and lobes parameters with cardiac cycle. Methods 18 patients with paroxysmal atrial fibrillation were examined by RT 3D-TEE. Three dimensional echocardiographic images of mitral annulus and lobes were collected from 3 cardiac cycles of left ventricular long axis. The dynamic values of mitral annulus and lobes were obtained by eSie Valves software. Results the mitral annulus area, circumference, anteroposterior diameter, interconjunctival diameter, non-plane angle, the angle between aortic annulus and mitral annulus were measured in systolic diastolic phase (P0.05), and the annulus height. The total area of anterior lobe and the area and length of A _ 1 A _ 2A _ 2 A _ 3 region were measured in systolic period (P 0.05), but there was no significant difference in the area and length of posterior lobe area and P _ (1) P _ (2) P _ (3) area between systolic and diastolic period (P _ (0.05). The consistency analysis of mitral valve values within and between groups showed good consistency. Conclusion RT 3D-TEE can be used to analyze the changes of mitral annulus and lobes parameters with cardiac cycle, and the consistency is good, which can provide reference for mitral valve repair and replacement surgery.
