Assessment of aortic and mitral valve regurgitation volumes by cardiovascular magnetic resonance in participants without valvular heart disease in the Hamburg City Health Study population.

ABSTRACT: An assessment of currently available cardiovascular magnetic resonance (CMR) methods to quantify aortic (AR) and mitral regurgitation (MR) in a large, population-based setting is lacking. The aim of this study was to evaluate CMR-based AR and MR quantification methods by quantifying AR and MR in participants without valvular heart disease in the population-based Hamburg City Health Study (HCHS). CMR was performed at 3T in the HCHS population. Aortic valve regurgitation volume (CMR-ARV) was directly obtained from 2D transaortic flow measurements. Mitral valve regurgitation volumes (CMR-MRV) were calculated by subtracting aortic forward flow volumes by Flow CMR from left ventricular stroke volumes by Cine CMR as currently recommended and by a method to account for potential confounding effec
