4D-flow CMR more accurately identifies hemodynamically significant aortic regurgitation, aiding reclassification of AR severity and guiding timely intervention.
Does 4D-flow CMR improve the assessment of aortic regurgitation severity compared to standard echocardiography and 2D phase-contrast CMR in patients with severe cardiomyopathy?
4D-flow CMR can accurately reclassify aortic regurgitation severity when standard imaging underestimates it, particularly in patients with heart rate variability.
Absolute Event Rate: 0% vs 0%
ABSTRACT Hemodynamically significant aortic regurgitation (AR) may be underestimated by standard echocardiography and 2D phase‐contrast CMR, particularly in patients with heart rate variability. This case highlights the additive role of 4D‐flow CMR in reclassifying AR severity, thereby identifying a significant pathology and helping to guide timely intervention.
