Transcatheter left atrial appendage occlusion (LAAO) is a low-risk procedure with a <1.0% risk of malposition.
An 80-year-old man with atrial fibrillation intolerant to apixaban underwent implantation of a 24 mm Watchman FLX device (Boston Scientific), which immediately shifted, exposing uncovered metal in the left atrium. Four weeks later, an AngioVac F22 catheter (AngioDynamics) was advanced into the left atrium and a 10-mm Raptor grasping forceps (Steris) was introduced via the AngioVac catheter. Using the Raptor, the Watchman FLX was grasped and with cautious, sustained force extracted into the AngioVac (Video 1) and out of the body intact (Figure 1). A 28 mm Amulet device (Abbott) was then implanted.
While alternative approaches to LAAO device retrieval have been described, this is to our knowledge the first report describing the use of an AngioVac catheter to extract a malpositioned Watchman FLX (Video 2) and achieving successful LAAO by replacement with an Amulet.
TAKE-HOME MESSAGE: Implanting proceduralists must be equipped to salvage high-risk complications such as device malposition.
经导管左心耳封堵术(LAAO)是一种低风险手术,器械位置不当的风险<1.0%。
一名80岁男性,患有房颤,对阿哌沙班不耐受,接受了24毫米Watchman FLX装置(波士顿科学公司)的植入,该装置立即发生移位,左心房出现未覆盖的金属部分。四周后,将一根AngioVac F22导管(AngioDynamics公司)推进左心房,并通过AngioVac导管引入一把10毫米的Raptor抓钳(史赛克公司)。使用Raptor抓钳抓住Watchman FLX,小心翼翼地持续用力将其拉入AngioVac(视频1),并完整地取出体外(图1)。随后植入了一个28毫米的Amulet装置(雅培公司)。
虽然已有文献描述了LAAO装置取出的替代方法,但据我们所知,这是第一份描述使用AngioVac导管取出位置不当的Watchman FLX(视频2)并通过更换为Amulet成功实现LAAO的报告。
植入手术医生必须具备处理器械位置不当等高风险并发症的能力。
