Accurate noninvasive evaluation of right heart hemodynamics is an essential component of the comprehensive cardiac examination. We aim to highlight recent advances in echocardiography allowing integration of measurements to obtain diagnostic accuracy.
Reports have advocated different imaging methods to describe right ventricular function and pulmonary artery pressure. Recent review articles provide comprehensive resources for the physician or technologist, and other articles compare echocardiography techniques, including strain imaging and three-dimensional echocardiography. We discuss the descriptions of the accuracy of Doppler echocardiography in comparison with cardiac catheterization.
Several measurements should be taken together for an accurate interpretation of right heart hemodynamics. We advocate the measurement of the tricuspid regurgitation gradient, pulmonary regurgitation gradient, pulmonary artery stroke distance (velocity time integral; VTI), evaluation of right ventricular function, and right atrial pressure.
准确的无创右心血液动力学评估是全面心脏检查的重要组成部分。我们旨在强调超声心动图的最新进展，这些进展可以整合测量结果以获得诊断准确性。
已有报告提倡使用不同的影像学方法来描述右心室功能和肺动脉压。最近的综述文章为医生或技术人员提供了全面的资源，其他文章则比较了超声心动图技术，包括应变成像和三维超声心动图。我们讨论了与心导管术相比，多普勒超声心动图的准确性描述。
为了准确解读右心血液动力学，应综合测量多个参数。我们主张测量三尖瓣反流梯度、肺动脉反流梯度、肺动脉射血距离（速度时间积分；VTI）、右心室功能评估和右心房压。
