经导管植入钳夹装置治疗三尖瓣膜关闭不全的应用解剖

Applied anatomy of transcatheter implantation of clamp device to treat tricuspid incomplete

目的为经导管植入钳夹装置治疗三尖瓣膜关闭不全提供三尖瓣区相关的应用解剖。方法解剖28例(男18,女10)外形大小正常的成年人心脏标本,观察三尖瓣膜的形态及与周围组织的解剖关系,测量与三尖瓣膜相关的数据。结果三尖瓣环周长为(109.4±14.2)mm,长径为(43.5±6.5)mm,短径为(29.3±5.4)mm。前瓣游离缘到附着缘最大距离为(22.3±4.1)mm,后瓣游离缘到附着缘最大距离为(20.5±3.8)mm。结论钳夹装置的大小和形状的设计应根据三尖瓣区解剖特点及与周边结构的关系来决定,钳夹三尖瓣的前后瓣叶可行。

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.
