This lateral view of the right heart in this sheep shows ventricular enlargement with tricuspid annular dilatation, a primary cause of functional tricuspid regurgitation (FTR)!

Advanced cases of TR may require tricuspid valve repair or replacement.

For preclinical evaluation of prosthetic tricuspid valve medical devices, selection of an appropriate animal model is essential.1 The ovine FTR model closely approximates human tricuspid pathology.

Learn more about tricuspid valve innovations in our interview with Prof. Hendrik Treede.

This image was acquired using IMMR’s 64-slice gated CT scanner with 3mensio 3D reconstruction software.
