The purpose of this review is to highlight the echo Doppler parameters that form the cornerstone for the evaluation of diastolic function as per the guideline documents of the American Society of Echocardiography (ASE) and the European Association of Cardiovascular Imaging (EACVI). In addition, the individual Doppler-based parameters will be explored, with commentary on the rationale behind their use and the multi-parametric approach to the assessment of diastolic dysfunction (DD) using echocardiography.
Previous guidelines for assessment of diastolic function are complex with modest diagnostic performance and significant inter-observer variability. The most recent guidelines have made the evaluation of DD more streamlined with excellent correlation with invasive measures of LV filling pressures. This is a review of the echo-derived Doppler parameters that are integral in the diagnosis and gradation of DD. A brief description of the physiological principles that govern changes in echocardiographic parameters during normal and abnormal diastolic function is also discussed for the appropriate diagnosis of DD using non-invasive Doppler echocardiography techniques.
本综述旨在强调根据美国超声心动图学会（ASE）和欧洲心血管影像协会（EACVI）的指南文件，构成舒张功能评估基石的超声多普勒参数。此外，还将探讨基于多普勒的各个参数，对其使用背后的原理以及使用超声心动图评估舒张功能障碍（DD）的多参数方法进行评论。
以往舒张功能评估指南复杂，诊断性能一般，且观察者间差异显著。最新指南使DD评估更简化，与左心室充盈压的有创测量具有良好相关性。本文综述了在DD诊断和分级中不可或缺的超声衍生多普勒参数。还讨论了在正常和异常舒张功能期间控制超声心动图参数变化的生理原理，以便使用无创多普勒超声心动图技术对DD进行恰当诊断。
