Summary
Left atrial appendage closure (LAAC) can cause perforation, but a novel sequential rescue technique using a second device successfully sealed the defect. This approach offers a potential treatment for acute LAAC-related perforations.
Area of Science:
- Cardiology
- Interventional Cardiology
- Medical Devices
Background:
- Left atrial appendage closure (LAAC) is crucial for preventing stroke in nonvalvular atrial fibrillation.
- Device-related left atrial appendage (LAA) perforation is a rare but serious complication, potentially leading to cardiac tamponade.
