Insights
Transcatheter closure is an evolving treatment for atrial septal defects (ASD), a common congenital heart issue. This review covers device evolution, outcomes, and complications, including device erosion concerns.
Area of Science:
- Cardiology
- Medical Devices
- Congenital Heart Disease
Background:
- Atrial septal defect (ASD) is a frequent congenital heart defect in children and adults.
- It accounts for a significant portion of congenital heart disease (CHD) diagnoses.
Purpose of the Study:
- To review the advancements in transcatheter closure for ASD.
- To discuss current indications, follow-up protocols, and patient outcomes.
- To highlight complications, particularly device erosion.
Main Methods:
- Literature review of transcatheter ASD closure techniques and devices.
- Analysis of clinical outcomes and complication data.
- Focus on device-related issues, including erosion.
Main Results:
- Transcatheter closure has evolved significantly as a treatment option for ASD.
- Established indications, follow-up strategies, and outcomes are presented.
- Device erosion remains a notable complication requiring attention.
Conclusions:
- Transcatheter ASD closure is a well-established and evolving therapeutic approach.
- Careful patient selection, device choice, and monitoring are crucial for optimal outcomes.
- Ongoing research aims to minimize complications like device erosion.
Abstract:
Atrial septal defect (ASD) is one of the most common congenital heart defects, accounting for 7%-10% of all congenital heart disease (CHD) in children and 30%-33% of defects diagnosed in adults with CHD. This review highlights the evolution of transcatheter ASD closure, indications, follow-up, outcomes, and complications with a focus on the erosion issue with certain devices.
