Anatomic considerations for tricuspid valve interventions

Abstract

The anatomy of the tricuspid valve produces several specific concerns when considering transcatheter repair or replacement strategies. The annular geometry, leaflet anatomy, and important neighboring cardiac structures must each be carefully addressed when planning tricuspid valve interventions. The variety of pathologies affecting the tricuspid valve, from organic causes to functional regurgitation, provides another layer of complexity in approaching repair or replacement. Most importantly, surgical treatment of the tricuspid valve is associated with high mortality, and development of catheter-based interventions may provide a desirable alternative to open surgical approaches.
