How to assess severe tricuspid regurgitation by echocardiography?
Abstract
Tricuspid regurgitation (TR) is the most commonly functional resulting from right ventricular (RV) (ventricular) remodelling by pressure/volume overload or right atrial (RA) remodelling (atrial) where annular dilatation is the main driver with underlying atrial fibrillation. Cardiac implantable electronic device-related (leaflet impingement, perforation, avulsion etc.) TR represents the second important group. Organic TR of different aetiologies is less frequent.
