Successful embolisation of coronary artery fistulas with the Azur® CX peripheral coil system in three paediatric...

Area of Science:

• Cardiology
• Pediatric Cardiology
• Interventional Cardiology

Background:

• Coronary artery fistulas (CAFs) are uncommon congenital heart defects.
• CAFs are often asymptomatic and incidentally found during cardiac imaging.
• Transcatheter closure is emerging as a preferred alternative to surgery due to reduced complications.

Purpose of the Study:

• To report the successful use of the Azur® CX Peripheral Coil System for transcatheter closure of coronary artery fistulas in pediatric patients.
• To highlight the system's efficacy in treating complex and tortuous vessels in children.

Main Methods:

• Retrospective analysis of three pediatric cases with coronary artery fistulas.
• Transcatheter embolization using the Azur® CX Peripheral Coil System via microcatheter.
• Evaluation of device suitability for tortuous pediatric coronary anatomy.

Main Results:

• Successful embolization of coronary artery fistulas in all three pediatric cases.
• The Azur® CX system demonstrated effective and controlled coil delivery in tortuous vessels.
• The hydrogel-coated coils facilitated optimal gap filling and vessel occlusion.

Conclusions:

• The Azur® CX Peripheral Coil System is a suitable and effective minimally invasive option for treating coronary artery fistulas in children.
• This coil system facilitates precise delivery and occlusion in challenging pediatric anatomies.
• Transcatheter coil embolization represents a safe and advantageous therapeutic approach for pediatric coronary artery fistulas.
