Tricuspid Valve Imaging and Right Ventricular Function Analysis Using Cardiac CT and MRI

Cardiac computed tomography (CT) and cardiac magnetic resonance imaging (CMR) can reveal the detailed anatomy and function of the tricuspid valve and right ventricle (RV). Quantification of tricuspid regurgitation (TR) and analysis of RV function have prognostic implications. With the recently available transcatheter treatment options for diseases of the tricuspid valve, evaluation of the tricuspid valve using CT and CMR has become important in terms of patient selection and procedural guidance. Moreover, CT enables post-procedural investigation of the causes of valve dysfunction, such as pannus or thrombus. This review describes the anatomy of the tricuspid valve and CT and CMR imaging protocols for right heart evaluation, including RV function and TR analyses. We also demonstrate the pre-procedural planning for transcatheter treatment of TR and imaging of postoperative complications using CT.

Automated summary

Cardiac CT and CMR can provide detailed information about the anatomy and function of the tricuspid valve and right ventricle, which has prognostic implications. With transcatheter treatment options for tricuspid valve diseases, evaluating the tricuspid valve using CT and CMR is important for patient selection and procedural guidance. Additionally, CT can help investigate post-procedural causes of valve dysfunction such as pannus or thrombus.
