Doppler velocity signals from regurgitant valve flow can be used to calculate pressure gradients across incompetent valves by a modification of the Bernoulli equation. Analysis of these gradients provides clinically useful, noninvasive information about cardiac chamber pressures. This study presents an unusual case of cardiomyopathy with panvalvular regurgitation which demonstrates the major methods of pressure analysis using Doppler signals from regurgitant valves.
来自瓣膜反流血流的多普勒速度信号可通过对伯努利方程进行修正来计算跨功能不全瓣膜的压力阶差。对这些压力阶差的分析可提供有关心腔压力的临床上有用的非侵入性信息。本研究报告了一例伴有全瓣膜反流的心肌病罕见病例，该病例展示了利用来自反流瓣膜的多普勒信号进行压力分析的主要方法。
