Migrating Amplatzer Septal Occluder (ASO) is a rare complication due to insufficient margins, especially large-hole Atrial Septal Defect (ASD). After deploying, ASO occasionally exposes the low margins, resulting in dislocated devices and embolization. The majority of embolizations happen right away after release. The embolized device must be removed using extended fluoroscopy and occasionally by open heart surgery. The device is released by unscrewing the cable while the snare holds the screw end. On Transesophageal Echocardiography (TEE), the device position is once again validated. If the device is stable, the snare is then removed.
迁移性Amplatzer房间隔封堵器（ASO）是一种因边缘不足导致的罕见并发症，尤其是大型房间隔缺损（ASD）。封堵器部署后，ASO偶尔会出现边缘过低的情况，导致装置移位和栓塞。大多数栓塞在释放后立即发生。必须使用延长透视检查，有时还需通过心脏直视手术取出栓塞的装置。在圈套器固定螺钉端的同时，通过拧松电缆来释放装置。经食管超声心动图（TEE）可再次验证装置位置。如果装置稳定，随后取出圈套器。
