Imaging Assessment of Tricuspid Regurgitation Severity.

Assessing the severity of tricuspid regurgitation remains a challenging task, and although echocardiography is the test of choice, significant limitations of the current recommendations exist. Newer methods have been used in current trials of transcatheter devices and may improve our understanding of the disease process. Cardiac magnetic resonance imaging and computed tomography angiography may play significant roles as adjunctive imaging modalities. This paper reviews the imaging modalities currently used to quantify tricuspid regurgitation severity.
