Multiparametric Approach to Identify a CMR-based Tricuspid Regurgitation Classification

The aims of this study are: 1. to explore a novel 2D-Cardiovascular magnetic resonance (CMR) indirect method for tricuspid regurgitation (TR) quantification (ATRIAL method) relying on right atrium variables, and assess its agreement with the traditional indirect method (involving right ventricle variables) and the direct method (based on through-plane phase contrast (PC) sequences on the tricuspid valve); 2. to assess the agreement of TR volume (RVol) and regurgitant fraction quantification from 2D-CMR methods with transthoracic echocardiography and 4DF-CMR methods; 3. to assess the diagnostic performance of 2D-CMR in classifying TR, in terms of RVol and regurgitant fraction, with respect to echocardiographic transthoracic echocardiography grades.
