Fluoroscopy-free Transcatheter Atrial Septal Defect Closure: A Simplified Approach

Area of Science:

• Cardiology
• Medical Devices
• Interventional Procedures

Background:

• Transcatheter atrial septal defect (ASD) closure is an alternative to surgical repair.
• Fluoroscopy-free techniques aim to reduce radiation exposure during these procedures.
• Limited data exists on simplified fluoroscopy-free approaches.

Purpose of the Study:

• To review fluoroscopy-free transcatheter ASD closure.
• To introduce a simplified technique avoiding pulmonary vein instrumentation.
• To assess the safety and efficacy of this simplified approach.

Main Methods:

• Retrospective analysis of patients undergoing fluoroscopy-free ASD closure.
• Comparison between a conventional technique (Group 1, n=9) and a simplified direct device placement approach (Group 2, n=23).
• Evaluation of procedural parameters, device implantation, and complications.

Main Results:

• Successful device implantation in all patients (n=32).
• Simplified approach (Group 2) showed a trend towards shorter procedural time (35 min vs 47 min).
• No acute or long-term complications, or need for reintervention in either group.

Conclusions:

• Fluoroscopy-free transcatheter ASD closure using a simplified approach is safe and effective.
• This method reduces procedure duration and minimizes instrumentation in the left atrium and pulmonary veins.
• Careful patient selection is crucial; wider applicability may increase with experience.
