Catheter Ablation of a Left Free-Wall Accessory Pathway via the Radial Artery Approach

Catheter ablation of the left free-wall accessory pathways (APs) is normally performed by the retrograde transaortic approach via a femoral artery or the transseptal approach. Here we report a case of an overt left free-wall AP, which was successfully ablated with a retrograde transaortic approach via the radial artery without any vascular complications. The patient has remained free of any symptoms or pre-excitation observed on the ECG during a 10-month post- ablation follow-up.
