To assess the value of measuring the aortic regurgitant jet diameter at its origin by M-mode colour Doppler imaging, 82 patients with aortic regurgitation underwent, within 72 h of each other, colour Doppler examination and angiography. After excluding one patient without colour Doppler aortic regurgitation and five with a highly eccentric regurgitant jet, we found a close relationship between the jet diameter at its origin measured by M-mode colour Doppler and the angiographic grade of aortic regurgitation (r = 0.88). A jet diameter greater than or equal to 12 mm identified severe aortic regurgitation (grade III or IV) with a sensitivity of 86.4% and a specificity of 94.4%. In 38 patients, the jet diameter correlated well with the regurgitant fraction measured by a combined haemodynamic-angiographic method (r = 0.88). A jet diameter greater than or equal to 12 mm identified a regurgitant fraction greater than or equal to 40% with a sensitivity of 88.2% and a specificity of 95.2%. This study indicates that the size of the regurgitant jet diameter at its origin measured by M-mode colour Doppler provides a simple and useful measure of the severity of aortic regurgitation. It may allow differentiation between mild or moderate and severe aortic regurgitation and evaluation of regurgitant fraction.
为评估M型彩色多普勒成像测量主动脉反流束起始处直径的价值，82例主动脉反流患者在彼此间隔72小时内分别接受了彩色多普勒检查和血管造影。排除1例无彩色多普勒主动脉反流的患者以及5例反流束高度偏心的患者后，我们发现M型彩色多普勒测量的反流束起始处直径与主动脉反流的血管造影分级之间存在密切关系（r = 0.88）。反流束直径大于或等于12 mm可诊断为重度主动脉反流（III级或IV级），敏感性为86.4%，特异性为94.4%。在38例患者中，反流束直径与通过血流动力学 - 血管造影联合方法测量的反流分数密切相关（r = 0.88）。反流束直径大于或等于12 mm提示反流分数大于或等于40%，敏感性为88.2%，特异性为95.2%。本研究表明，M型彩色多普勒测量的反流束起始处直径大小为评估主动脉反流的严重程度提供了一种简单且有用的方法。它可用于区分轻度或中度与重度主动脉反流，并评估反流分数。
