Summary
Transcatheter closure of giant atrial septal defects (ASDs) is now possible using coupled occluder devices. This innovative technique offers a viable alternative for inoperable patients with prohibitive risks.
Area of Science:
- Cardiology
- Interventional Cardiology
- Medical Devices
Background:
- Giant secundum atrial septal defects (ASDs) typically require surgical repair due to limitations in transcatheter closure.
- Innovative percutaneous strategies are being explored for patients with prohibitive surgical risks.
