Emergent surgical removal of a migrated atrial septal defect occluder: case report

Abstract

Abstract Background 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). Case introduction 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. Conclusion This technique provides a safe method for surgical removal of malposition and migration ASD occluder device.
