Reproducibility of mild to moderate regurgitation of all heart valves by magnetic resonance imaging

Introduction Cardiac magnetic resonance imaging (CMR) is regarded as the gold standard for evaluation of left and right ventricular volumes and ejection fraction. Assessment of valve regurgitation can be performed by flow measurement in the great arteries for the aortic and pulmonary valve. Subtraction of ventricle stroke volume and flow measurement in the affiliated great artery results in regurgitation volume of the corresponding atrioventricular valve. Aim of this study was to evaluate the reproducibility of valve regurgitations considering intraand interobserver variability in patients with mild to moderate valve regurgitation.
