Abstract Transthoracic echocardiography (TTE) is the first‐line and most useful imaging modality for evaluating diastolic dysfunction (DD). Cardiovascular magnetic resonance (CMR) has not been fully evaluated for this task. We investigated the utility of CMR for DD evaluation.Thirty‐one patients with a recent TTE (within 4 months) were prospectively enrolled, along with 12 healthy age‐matched subjects. CMR imaging was performed at 1.5 T to assess diastolic function by quantifying mitral inflow velocities (E and A), mitral annular velocities (e’), and left atrial volume (LAVi). Measurements by TTE and CMR were compared using regression. The diagnostic accuracy of CMR for DD was determined.CMR derived E, A, E/A, e’ and E/e’ all correlated moderately to strongly with TTE, and more strongly when comparing studies performed closer in time (E: r = 0.68, E deceleration time: r = 0.82, A: r = 0.78, e’ r = 0.75, E/e’: r = 0.80, p = 0.001; LAVi: r = 0.79, p |
