Compare and contrast tricuspid and mitral valve anatomy: interventional perspectives for transcatheter tricuspid valve therapies

Abstract

Moving treanscatheter valve intervention towards atrioventricular (AV) valves implies increasing complexity. Part of the knowledge that has been generated during the development of mitral devices can be transferred to the tricuspid valve (TV). A deep understanding of the peculiar anatomy of the TV and of the right heart chambers, with differences and similarities between the two AV valves is fundamental to overcome the specific challenges related to transcatheter TV therapies. The aim of this report is to explore similarities and differences between mitral and tricuspid apparatus, and their interventional implications.
