Key result
Prominent pulmonary vein signals in the left atrium during color Doppler examination can mimic mitral regurgitation and confound the assessment of its severity.
Prominent pulmonary venous flow can mimic mitral regurgitation on color Doppler, representing a potential pitfall in assessing MR severity.
Answers are grounded in this paper and cite their sources.
Be aware that prominent pulmonary vein signals may mimic MR on color Doppler, risking severity misjudgment; Level 5 data leaves open validation in larger cohorts.
The present case highlights a potential pitfall in assessing mitral regurgitation severity due to the presence of similar colored prominent pulmonary vein signals in the left atrium during color Doppler examination.
