Insights
A device used to close atrial septal defects migrated to the aortic valve and left main coronary artery. Emergent surgery was needed to retrieve the device in a critically ill child.
Area of Science:
- Cardiology
- Medical Device Technology
- Pediatric Cardiac Surgery
Background:
- Atrial septal defects (ASDs) are commonly closed using percutaneous devices.
- Device embolization is a rare but serious complication of transcatheter procedures.
- Coronary artery ostial obstruction can lead to acute myocardial infarction.
Observation:
- An atrial septal defect closure device embolized after implantation.
- The embolized device lodged at the aortic valve and the left main coronary artery ostium.
- The patient was a critically ill child requiring immediate intervention.
Findings:
- Successful emergent surgical retrieval of the embolized ASD closure device.
- Restoration of coronary blood flow and hemodynamic stability.
- Histopathological analysis of the retrieved device and surrounding tissue.
Implications:
- Highlights the risk of device embolization in ASD closure.
- Underscores the importance of vigilant monitoring and prompt management of complications.
- Informs procedural modifications and device design to minimize embolization risks in pediatric patients.
Abstract:
We present a case of an atrial septal defect closure device that embolized to the aortic valve and left main coronary artery ostium, which required emergent surgical retrieval in an unstable child.
