Quantifying mitral regurgitation with cardiovascular magnetic resonance (CMR) involves indirect calculation, which increases the potential for error. We examined a direct quantification method using velocity mapping across the mitral valve, which may be less susceptible to error, and also examined the effect of heart rate variability on both techniques. Fifty-five patients underwent mitral regurgitation quantification with CMR by the direct method and two indirect methods—the standard method… CONTINUE READING
