Functional tricuspid regurgitation (FTR) is the most frequent aetiology of tricuspid valve (TV) pathologies and is associated with increased morbidity and mortality1. Assessment and management of FTR has developed substantially, in particular because of the increased understanding of the long-term consequences of TV disease together with continued advances in transcatheter techniques2. Catheter-based repair requires detailed knowledge of the anatomy of the TV apparatus for planning and periprocedural assistance3. Particularly important is the right coronary artery (RCA), which is separated from the tricuspid annulus (TA) by only a few millimetres4.

This study comprehensively assessed the dynamic anatomic ...
