The tricuspid valve is a complex dynamic apparatus made up of many different closely linked structures: the annulus, the three leaflets, the chordae, the papillary muscles and the right ventricle. Other nearby structures, such as the coronary sinus ostium, the conduction system, the membranous septum, and the right coronary artery must be taken into account when dealing with the tricuspid. Annulus dilation and leaflet tethering due to right ventricular remodeling are the 2 major mechanisms responsible for most tricuspid regurgitation cases. Precise knowledge of tricuspid anatomy and function, as well as careful preoperative planning, is fundamental for successful transcatheter tricuspid procedures.

Abstract
The tricuspid valve is a complex dynamic apparatus made up of many different closely linked structures: the annulus, the three leaflets, the chordae, the papillary muscles and the right ventricle. Other nearby structures, such as the coronary sinus ostium, the conduction system, the membranous septum, and the right coronary artery must be taken into account when dealing with the tricuspid. Annulus dilation and leaflet tethering due to right ventricular remodeling are the 2 major mechanisms responsible for most tricuspid regurgitation cases. Precise knowledge of tricuspid anatomy and function, as well as careful preoperative planning, is fundamental for successful transcatheter tricuspid procedures.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
