Assessment of diastolic dysfunction in patients with acute coronary syndrome and preserved systolic function: comparison between Doppler transthoracic echocardiography and velocity-encoded cardiac magnetic resonance

摘要

Objectives Transthoracic echocardiography (TTE) remains the mainstay diagnostic imaging tool for the assessment of diastolic dysfunction. However, velocity-encoded phase-contrast imaging permits evaluation with cardiac magnetic resonance (CMR) with excellent capabilities to assess blood flow and myocardial tissue motion. We evaluated the feasibility of measuring mitral blood flow, mitral annular velocity and pulmonary vein flow in assessing diastolic dysfunction in acute coronary syndrome (ACS) patients.
