Mri assessment of diastolic dysfunction using the echocardiographic criteria of diastolic mitral blood flow, lateral wall motion velocity and pulmonary vein flow

Introduction In echocardiography (EC), classification of diastolic dysfunction (DD) is widely accepted and mainly assessed using three criteria (figure1): mitral blood flow (MBF, E-A-curve), lateral wall velocity (LWV, S-E`-A`-curve) and pulmonary vein flow (PVF, S-D-AR-curve). With these three characteristic flow and velocity patterns and their ratios E/A, E/E ́ and S/D, regular diastolic function can be clearly distinguished from three degrees of DD (I-III°). Cardiovascular magnetic resonance (CMR) has excellent capabilities to assess blood flow and myocardial tissue motion using phase contrast (PC-CMR) imaging but has not been used to classify diastolic function similar to the EC approach.
