Abstract

Peri-device leak (PDL) following left atrial appendage occlusion (LAAO) is particularly problematic in patients with both high thromboembolic and bleeding risk. We present a case series of three patients with atrial fibrillation and high bleeding risk. All three patients underwent LAAO with a Watchman™ and were found to have PDL on follow-up imaging. All three patients underwent successful PDL closure with an Amplatzer™ duct occluder II device with no complications noted. These cases demonstrate that PDL closure can be safely and effectively performed via a plug-based approach. Imaging is critical in determining candidacy for and method of PDL closure.
左心耳闭塞术后器械周围漏的塞式封堵一例
左心耳闭塞(LAAO)后的装置周围泄漏(PDL)在血栓栓塞和出血风险高的患者中尤其成问题。我们提出一个病例系列的三个病人心房颤动和高出血的风险。所有3例患者均使用Watchman™进行LAAO检查,并在随访影像中发现PDL。所有3例患者均使用Amplatzer™II型导管闭塞器成功闭合PDL,无并发症发生。这些案例表明,通过基于插件的方法可以安全有效地执行PDL关闭。影像学是决定PDL闭合的候选性和方法的关键。
