Coronary Occlusion to Avoid Heat Convection During Radiofrequency Ablation of an Accessory Pathway

Radiofrequency ablation (RFA) of right free wall accessory pathway can be compromised by the proximity of the right coronary artery (RCA). We report a case of with a right sided accessory pathway despite previous RFA attempts with immediate loss of pre-excitation. The accessory pathway was mapped
