Insights
Device migration after atrial septal defect closure is a rare but serious complication. Vigilant monitoring is crucial for early detection and management of such events following percutaneous procedures.
Area of Science:
- Cardiology
- Medical Devices
- Surgical Complications
Background:
- Large inter-atrial defects can cause symptoms like shortness of breath and palpitations.
- Percutaneous closure is a common treatment for atrial septal defects.
Abstract:
We present the case of a 32-year-old female patient who presented at the cardiology consultation with shortness of breath and palpitations. A large inter-atrial defect was identified through echocardiography, prompting the cardiology team to perform a percutaneous closure procedure using the Amplatzer Atrial Septal Occluder (Abbott Laboratories, Abbott Park, IL, USA). Seven weeks later, a migration of the prosthetic device into the left ventricular outflow tract was diagnosed. A surgical procedure was immediately performed to explant the device and repair the defect. This case highlights the importance of vigilant monitoring in patients undergoing percutaneous closure procedures to detect severe complications such as device migration at an earlier stage.
