Abstract

Abstract:

Objective　To understand the anatomical characteristics of tricuspid valves and provide anatomical basis for transcatheter implantation of clamp device to treat tricuspid incomplete. Methods 28 adult heart specimens (18 male and 10 female) were dissected and measured. Results　The long diameter, short diameter and the perimeter of tricuspid valves of adult were (43.5±6.5) cm, (29.3±5.4) cm, and (109.4±14.2) mm, respectively. The maximum distance of the anterior leaflet from the free margin to the attachment margin was (22.3±4.1)mm, The distance of the posterior leaflet from the free margin to the attachment margin was (20.5±3.8) mm. Conclusions The size and shape of the clamp device should be designed according to the anatomical characteristics of the tricuspid area and the relationship with surrounding structures. It is feasible for clamping the anterior leaflet and the posterior leaflet of tricuspid.
