Doppler echocardiographic (Echo) measurements of the mitral and pulmonary venous flow have been used to assess diastolic dysfunction (DD). Velocity-encoded cardiac magnetic resonance (Ve-CMR) can measure similar parameters and may potentially be used for the assessment of DD.


To assess the correlation of Ve-CMR with Echo in assessing mitral inflow E/A ratio, left atrial (LA) size, and pulmonary vein (PV) flow.


We prospectively enrolled 22 outpatients with a mitral inflow pattern by Echo that was normal (8), impaired relaxation (7), pseudo-normal (2), or restrictive (5). The mean left ventricular ejection fraction (LVEF) was 60.8 and two patients had left ventricular hypertrophy on echo. Ve-CMR was performed within 2 hours of the Echo. The following indices were measured: LA size, mitral inflow E-velocity (E), A-velocity (A), E/A ratio, PV waves (S, D and A).


The mean age of the patients was 51 years. The average Echo mitral inflow absolute velocities were close to double the Ve-CMR {Echo E-velocity = 85.8 cm/sec vs. Ve-CMR E velocity = 41.4 cm/sec, Echo A-velocity 70 cm/sec vs. Ve-CMR A-velocity 32.5 cm/sec}. The average E/A ratio was 1.41 by echocardiogram and 1.48 by Ve-CMR. There was a significant correlation in LA size and Mitral inflow E/A ratio between Ve-CMR and Echo (Rho = 0.9, p < 0.01; Rho = 0.88, p < 0.01, respectively). There were no significant correlations in PV waves (Rho = 0.12, p = 0.58). Figure 1

Correlation between Ve-CMR and Doppler echo derived values was tested using Spearman's rank correlation coefficients. There was significant correlation between left atrial size and E/A ratio. A: LA size (R = 0.9, p-value < 0.05), B: E/A ratio (R = 0.88, p-value < 0.05), but not C: (R = 0.12, p = 0.58). LA; left atrium, PV, pulmonary vein.


Ve-CMR has a very high correlation with Echo in the assessment of mitral inflow E/A ratio and LA size. Ve-CMR maybe useful for the assessment of diastolic dysfunction.
