Summary
This review synthesises the role of multi-modality imaging in patient selection and procedural guidance for transcatheter tricuspid valve interventions. It discusses how echocardiography, computed tomography, cardiovascular magnetic resonance, and right heart catheterisation enable accurate phenotyping of tricuspid regurgitation and associated right heart pathology. The authors present selection criteria and intraprocedural imaging strategies for the main commercially available transcatheter techniques: edge-to-edge repair, orthotopic and heterotopic replacement, and valve-in-valve procedures.
Regional applicability
The imaging protocols and device selection framework described are applicable to clinical practice in the United Kingdom, where transcatheter tricuspid intervention is an emerging technique. Transferability depends on local access to multi-modality imaging infrastructure and training in these novel percutaneous approaches.
Key measures
Anatomical and functional characteristics of tricuspid regurgitation; right heart and pulmonary vasculature phenotyping; device selection criteria; procedural success factors
Outcomes reported
The review synthesises imaging modalities (echocardiography, CT, CMR, right heart catheterisation) for assessing tricuspid regurgitation anatomy and function. It presents patient selection criteria and intraprocedural imaging guidance for transcatheter repair/replacement techniques including edge-to-edge repair, orthotopic and heterotopic replacement, and valve-in-valve procedures.
