ABSTRACT:
The disclosure relates generally to cryogenic techniques the mapping and ablation of arrhythmias or tachycardia in atrial or ventricle heart muscles and, more particularly, to an epicardial approach which either addresses the heart directly through an open chest or employs transcutaneous subxiphoid pericardial approach for the mapping and ablation of tachycardia using laparoscopy/thoracoscopy techniques via an intrapericardial/epicardial approach. The technique involves electrograms recording and cryogenic verification and ablation, although RF ablation can also be used.
