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.
瓣环、三个瓣叶、腱索、乳头肌和右心室。在处理三尖瓣问题时，必须考虑其他附近的结构，如冠状窦口、传导系统、膜性间隔和右冠状动脉。右心室重塑导致的瓣环扩张和瓣叶束缚是大多数三尖瓣反流病例的两个主要机制。精确了解三尖瓣的解剖结构和功能，以及仔细的术前规划，是经导管三尖瓣手术成功的基础。
