Essential roles for CT and MRI in timing of therapy in tricuspid regurgitation

Abstract

The rapid development of transcatheter tricuspid valve intervention (TTVI) therapies has quickly provided the opportunity to improve patient selection and procedural planning for patients with significant tricuspid regurgitation (TR) considered at high surgical risk. This review focuses on the contributions which both computed tomography angiography and cardiac magnetic resonance can provide in the better understanding of the natural history of TR, in the comprehensive anatomical and functional assessment of right heart involvement and in the timing and planning for TTVI. We also discuss areas of potential importance such as the quantification of response to TTVI, which will be informative for future trials.
