Multimodality Imaging of Tricuspid Valve Disease at the Dawn of Transcatheter Intervention

There is growing interest in the impact of tricuspid valve disease. Multiple studies have demonstrated that the presence of tricuspid regurgitation, either in its isolated form or when co-existent with other valvular disease, leads to poor outcomes. Surgical repair or replacement is an option for a limited population fulfilling specific anatomic and clinical criteria. Transcatheter intervention of tricuspid valve disease offers a potentially valuable alternative to surgical treatment. The success and outcomes of the intervention are heavily dependent on understanding the tricuspid valve anatomy and pathophysiology. Multimodality imaging is the cornerstone for pre-procedural, peri-procedural as well as post-procedural assessment and management. This section will discuss the pathophysiology of tricuspid valve disease and the role of different imaging modalities in the diagnosis and preprocedural evaluation of the RV and TV. We will also discuss the role of imaging in guiding the choice of therapeutic intervention and post procedural surveillance and management.
