The left ventricular internal dimension at end diastole, interventricular septal thickness at end diastole and left ventricular posterior wall thickness at end diastole were measured in the parastemal long axis view by transthoracic two-dimensional echocardiography, and to calculate left ventricular ejection fraction with Teichholtz formula and left ventricular mass with modified Devereux formula, left ventricular mass index=LVM/body surface area. From the apical four chamber and two chamber view, the basical segment and middle segment of interventricular septal, left ventricular lateral wall, anterior wall and inferior wall were obtained by tissue Doppler imaging, Regional left ventricular relaxation asynchrony index was calculated.

应用二维超声心动图在胸骨旁左心室长轴观测量左心室舒张末期内径、室间隔和左心室后壁舒张末期厚度，采用Teichholtz公式计算左心室射血分数，采用Devereux校正公式计算左心室心肌质量，左心室心肌质量指数=左心室心肌质量/体表面积；在心尖四腔心和心尖两腔心切面，应用组织多普勒成像获取室间隔、左心室侧壁、前壁和下壁的基底段和中间段8个心肌节段沿左心室长轴运动的速度频谱，测算左心室局部心肌松弛不同步性指数(regional left ventricular relaxation asynchrony index， AI)；在心尖四腔心切面，应用彩色M型多普勒超声心动图测量左心室舒张早期血流传播速度。

The purpose of the present investigation is to evaluate the distensibility of both ascending and descending aorta in different type of aortic dissection by comprehensive transthoracic echocardiography and transesophageal echocardiography.

本研究在上一研究的基础上，联合应用常规经胸超声和经食管超声，对不同类型主动脉夹层(DeBakeyⅠ型夹层12例及Ⅲ型夹层11例)之不同部位主动脉扩张性进行更进一步深入对比研究，试图揭示主动脉夹层血管弹性异常的根本原因。

Effectiveness evaluation by transthoracic echocardiography, electrocardiography was applied at 24 hours, 1 month, 3 months and 6 months after the procedure.

术中进行造影或经胸超声心动图检查，分别于术后24h，1、3、6个月随访TTE及心电图，观察疗效。

Methods— Morphologic features of ASD and VSD were demonstrated by specialized echocardiographic section using a transthoracic probe. En face views of secundumASD and perimembranous and outflow tract or doubly committed subarterial VSD were imaged with interatrial septal section and inflow and outflow interventricular septal section on parasternal or apical position, respectively.

使用特殊的超声心动图切面显示 ASD 和 VSD 的平面形态学特征，在胸骨旁或心尖位置，使用房间隔切面、流入道和流出道室间隔，分别显示继发孔型 ASD 、膜周部和流出道或双动脉干下型 VSD 的平面形态学特征。
