Catheter ablation of a left free-wall accessory pathway via the radial artery approach

Area of Science:

• Cardiology
• Electrophysiology
• Vascular Access

Background:

• Catheter ablation is standard for left free-wall accessory pathways (APs).
• Conventional approaches include retrograde transaortic via femoral artery or transseptal routes.
• Left free-wall APs present unique ablation challenges.

Observation:

• A case report details ablation of an overt left free-wall AP.
• The procedure utilized a retrograde transaortic approach.
• Access was gained via the radial artery, avoiding femoral or transseptal routes.

Findings:

• Successful ablation of the left free-wall accessory pathway was achieved.
• The retrograde transaortic approach via the radial artery caused no vascular complications.
• The patient remained symptom-free with no ECG-observed pre-excitation at 10-month follow-up.

Implications:

• The radial artery approach is a viable and safe alternative for ablating left free-wall APs.
• This technique may reduce vascular complications associated with traditional femoral access.
• Further studies could explore the broader application of radial artery access in AP ablation.
