Abstract
Catheter ablation with radiofrequency (RF) is the treatment of choice for atrio-ventricular reentrant tachycardias. In case of posterior or postero-lateral accessory pathways, epicardial RF ablation from within the coronary sinus (CS) may be warranted, but since both the left circumflex (LCx) coronary artery and the CS lie on the epicardial surface of the atrioventricular groove, LCx injury with possible acute occlusion or sub-total occlusion can occur. This case report describes the management of an acute injury to the distal LCx during RF ablation providing, for the first time in vivo and in man, details of vessel wall changes by intracoronary imaging application.
