Transcatheter closure of muscular ventricular septal defects (VSD) remains a safe and effective method with low complication rates. However, device migration can pose a significant challenge to interventional cardiologists due to potential mortal consequences. A 21-year-old female presented to our clinic with exertional dyspnea and was diagnosed with a muscular VSD. The defect was percutaneously closed using an Amplatzer occluder device. On the first post-procedural day, the patient experienced repeated episodes of coughing and mild hemoptysis. Imaging revealed migration of the VSD occluder device to the right pulmonary artery (PA). Percutaneous retrieval of the device was then decided upon. The right PA was accessed using a hydrophilic guidewire and a pigtail catheter. This catheter was exchanged for an 8-Fr sheathless guide catheter, and a 6-Fr Judkins right catheter was advanced into the right PA through the sheathless guide catheter using the mother-and-child technique. Multiple attempts using a snare were made to retrieve the migrated device. Eventually, the proximal marker point, the hub of the device, was grasped and pulled back from the PA, then externalized through the sheath without the need for surgical cutdown. Our report represents a case of complete percutaneous retrieval of an embolized VSD occluder device from the PA.
