Atrial septal defect (ASD) closure has been widely accepted and is now routinely performed using a percutaneous approach under especially echocardiographic guidance Transesophageal echocardiography (TEE). One major complication is dislocation of occluder device during or after the device implantation. Surgical removal may be required, especially when the device stuck in the left ventricular outflow tract (LVOT).
A 21-year-old female was admitted to our department for percutaneous closure of secundum ASD. Percutaneous closure under the guidance of TEE was recommended for the patients. During device implantation, the TEE showed dislocation of the 22 mm ASD occluder device, stucked into the LVOT and behind the anterior mitral leaflet, producing severe LVOT obstruction Fig. 1). We herein present a safe and quick technique for surgical removal of an ASD occlude device located in the LVOT.
This technique provides a safe method for surgical removal of malposition and migration ASD occluder device.
房间隔缺损（ASD）封堵术已被广泛接受，现在通常在超声心动图的特别引导下经皮进行。经食管超声心动图（TEE）是一种主要的并发症是封堵器装置在植入过程中或之后脱位。可能需要进行手术切除，特别是当装置卡在左心室流出道（LVOT）时。
一名 21 岁女性因房间隔继发孔缺损（ASD）来我院就诊。建议患者在 TEE 引导下行经皮封堵术。在装置植入过程中，TEE 显示 22mm ASD 封堵器装置脱位，卡在左心室流出道（LVOT）和前二尖瓣叶后面，导致严重的 LVOT 阻塞（图 1）。本文介绍了一种安全、快速的方法，用于取出位于 LVOT 的 ASD 封堵器装置。
该技术为经皮封堵器装置错位和迁移的手术取出提供了一种安全的方法。
