This study quantitatively evaluated the phasic right heart morphology of candidate patients for a transcatheter tricuspid valve intervention (N=32) and subjects with trace to no regurgitation (N = 14).Cardiac computed tomography angiography (CCTA) transthoracic/transesophageal echocardiography (TTE/TEE) images were analyzed using dedicated research clinical software. Using CCTA, atrial ventricular volumes, annulus dimensions, annulus-to-right coronary artery (RCA) distances, circumferential topography annular tissue shelf, vena cava dimensions (inferior superior), positions, axis angles, excursions quantified. TTE/TEE, leaflet geometry, regurgitation, hemodynamics, function Measurements within between groups compared regression analyses explore relationships features.The position orientation shelf presented first time. The patient group exhibited greater chamber enlarged cava, distended positional shallowing geometric distortion, distention, moderate or impaired function. Atrial volume correlated strongly directional positions as well dimensions. Annulus-to-RCA distances comparable groups.This provides new further insight functional characteristics intervention. These data provide platform from which these can continue be better understood improving system design use.
