CIT 2018:中国已完成千例“不开胸换瓣”手术,有2个国产瓣膜上市

2018-03-26 佚名 中国循环杂志

经导管主动脉瓣置换术(TAVR)已经发展了15个年头了,在CIT2018上,四川大学华西医院陈茂教授与就此回顾了中国TAVR的发展历程,以及TAVR的革新。

经导管主动脉瓣置换术(TAVR)已经发展了15个年头了,在CIT2018上,四川大学华西医院陈茂教授与就此回顾了中国TAVR的发展历程,以及TAVR的革新。


已完成1000例TAVR手术

陈茂介绍说,自2010年10月3日葛均波院士在上海成功完成国内首例TAVR术至今,有数据统计中国大陆已完成近1000例TAVR手术。

据不完全统计,国内大约有50个中心已至少完成1例TAVR术,但只有4个中心拥有超过50例手术的经验。

2个国产瓣膜已上市

国产主动脉瓣膜产品从研发到试验也进行得如何如荼,其中已进入商业化推广的是Venus A-Valve和J-Valve。Venus A-Valve在中国的选用率达54%。

此外,MicroPort VitaFlow Valve正在等待CFDA审核;SAPIEN XT Valve,已展开临床试验。Taurus One首次人体试验已完成,并展开临床试验;CoreValve和Lotus Valve正在计划临床试验。

中国患者钙化和二叶式主动脉瓣较高

中国主动脉瓣狭窄患者有其独特的解剖学特点:一是主动脉瓣膜存在较严重钙化现象;二是近40%的患者为二叶式主动脉瓣,远高于西方人群。严重瓣膜钙化和二叶式主动脉瓣畸形使TAVR在中国面临更大的挑战。

二叶式主动脉瓣钙化往往严重,直视下瓣环呈鱼唇形,瓣膜释放后展开不易充分,易形成瓣周漏、瓣膜移位等并发症。
