INTRODUCTION
Despite maturing experience and growing procedural familiarity, there remain challenges in percutaneous left atrial appendage (LAA) closure due to anatomical complexities.
METHODS
We report a complex and extremely large LAA that was successfully closed percutaneously using a LAmbre Closure System (Lifetech Scientific Corp.). Cardiac computed tomography angiography demonstrated a gigantic multilobed LAA measuring 48 × 45.3 mm at the level of the ostium that cannot be occluded by the currently approved LAA closure devices in Canada.
RESULTS
The manufacturer custom-made a LAmbre 30/50 mm (lobe/disc) device to fit this patient's LAA according to his CTA, which was successfully deployed under fluoroscopy and transesophageal echocardiogram guidance without procedure-related complications.
CONCLUSION
The LAmbre device may be considered to close very large LAAs.
简介
尽管经验日趋成熟，手术操作也愈发熟练，但由于解剖结构复杂，经皮左心耳（LAA）封堵术仍存在挑战。
方法
我们报告了一例复杂且极其巨大的左心耳，成功地使用 LAmbre 封堵系统（Lifetech Scientific Corp.）经皮封堵。心脏计算机断层扫描血管造影显示，在开口水平有一个巨大的多叶左心耳，大小为 48×45.3mm，不能用加拿大目前批准的左心耳封堵装置来封堵。
结果
制造商根据患者的 CTA 定制了一个 LAmbre 30/50mm（叶/盘）装置，以适应该患者的左心耳，该装置在透视和经食管超声心动图引导下成功部署，没有与手术相关的并发症。
结论
LAmbre 装置可用于封堵非常大的左心耳。
