Electrical disconnection of the coronary sinus may be necessary to isolate triggers during radiofrequency ablation for chronic atrial fibrillation.
We report a case of radiofrequency catheter ablation for chronic atrial fibrillation, in which electrical disconnection of the coronary sinus was necessary to isolate a trigger initiating atrial fibrillation. (J Cardiovasc Electrophysiol, Vol. 15, pp. 364‐368, March 2004)
Sanders et al. (Mon,) studied this question.
