To describe the cases of percutaneous valve failure following implantation of the Medtronic Melody™ and the Edwards Sapien™ valve in the tricuspid position.
There have been recent reports of the use of percutaneously delivered valves to manage failing bioprosthetic tricuspid valves. Total patient numbers remain small and follow-up times are limited.
We describe four procedures in three patients from two centers where implantation of percutaneous valves within the scaffold of a bioprosthetic tricuspid valve was technically successful but there was early valve failure.
In all cases, immediate results suggested excellent valve function; however, valve failure occurred early in three and later in one. Two patients elected for valve explantation and surgical placement of a further tricuspid valve. The third patient underwent a second percutaneous valve-in-valve procedure though this valve is also showing early signs of failure.
Transcatheter placement of percutaneous valves in the tricuspid position is technically a relatively straightforward procedure but early valve failure raises some concerns about the viability of the valve in this position, at least in some patients.
描述在三尖瓣位置植入美敦力 Melody™ 和爱德华兹 Sapien™ 瓣膜后发生经皮瓣膜故障的病例。
最近有报道称使用经皮输送瓣膜来治疗生物瓣三尖瓣功能衰竭。总的患者人数仍然较少,随访时间有限。
我们描述了来自两个中心的三例患者的四个手术程序,其中经皮瓣膜在生物瓣三尖瓣支架内的植入技术上是成功的,但早期出现瓣膜故障。
在所有情况下,即刻结果提示瓣膜功能良好;然而,三例患者早期发生瓣膜故障,一例患者晚期发生瓣膜故障。两名患者选择进行瓣膜取出和进一步的三尖瓣手术置换。第三位患者接受了第二次经皮瓣中瓣手术,但该瓣膜也出现了早期故障迹象。
经皮瓣膜在三尖瓣位置的植入技术上相对简单,但早期瓣膜故障引起了对该位置瓣膜生存能力的一些关注,至少在某些患者中是这样。
