Summary
Percutaneous closure of atrial septal defects (ASD) is rising. A rare complication of device closure is intracardiac fistula formation, emphasizing careful patient selection, especially those with deficient aortic and superior rims.
Area of Science:
- Cardiology
- Interventional Cardiology
- Medical Devices
Background:
- Percutaneous closure of atrial septal defects (ASD) is increasingly favored over surgical repair due to its safety and ease.
- Device-related complications, including perforation and displacement, necessitate surgical intervention.
- Intracardiac fistula formation is a rare but serious complication following ASD device closure.
Observation:
- This report details a case of intracardiac fistula formation after percutaneous ASD device closure.
- The complication occurred during medium-term follow-up.
- The underlying mechanism is presumed similar to previously reported instances.
Findings:
- Device perforation leading to intracardiac fistula formation is a potential complication of ASD device closure.
- This specific case highlights the occurrence during medium-term follow-up.
- The mechanism may involve device interaction with cardiac structures.
Implications:
- Careful patient selection is crucial to minimize the risk of ASD device closure complications.
- Particular caution is advised for ASD cases with deficient aortic and superior rims.
- Further research into device-tissue interactions may refine procedural safety and patient outcomes.
