TAPSE较容易获取,是测量RV轴向功能的一项指标。侧壁三尖瓣环TAPSE < 16mm提示RV收缩功能不全,尽管它测量RV轴向功能,但与放射性核素等方法测量的RV EF, 2D RV FAC和2D RV EF等RV整体收缩功能指标具有较好的相关性。 二维面积变化分数...

Currently, after the Predictors of Response to CRT and the Mayo Clinic studies,99 which support the indications in clinical guidelines, there is no definite role for the echocardiographic measurement of mechanical dyssynchrony to indicate the need for CRT in patients with heart failure. There is a...

On the right are the corresponding H/CL (heart/contralateral lung) lung-ratio methodology with measurement of mean counts per pixel for target (heart) and background (contralateral chest). As shown in this figure, the ROI’s (region of interest) should be positioned to minimize overlap with ...

2D = Two-dimensional,二维 摘要 评估右心室对预测有心肺疾病症状表现的患者的发病率和死亡率具有重要意义。然而,系统化评估右心室功能缺乏统一的标准。这其中部分原因是既往过于关注左心功能的评估,缺少右心超声成像方法的探索,及缺乏对右室大小和功能的正常参考值方面的超声诊断研究。
It is essential in clinical practice to use an integrative approach when grading the severity of stenosis, combining all Doppler and 2D data, and not relying on one specific measurement. Loading conditions influence velocity and pressure gradients; therefore, these parameters vary depending on intercurr...
