Radiofrequency catheter ablation in the coronary sinus for atrial fibrillation carries a risk of acute occlusion of the left circumflex coronary artery.
Alerts to LCx occlusion risk during CS ablation; hypothesis-generating case report leaving optimal prevention open.
Occlusion of LCX During RF Catheter Ablation. We report a case of acute occlusion of the left circumflex coronary artery during catheter ablation in the coronary sinus to complete the linear lesion between the postero-lateral mitral annulus and the left inferior pulmonary vein for the treatment of atrial fibrillation.
