Abstract:
Epicardial location of accessory AV pathways may be responsible for the failure of conventional endocardial radiofrequency catheter ablation. Transcutaneous epicardial instrumentation provides access to the normal pericardium with no need for invasive thoracotomy or thoracoscopy. We report the case of successful epicardial mapping and ablation of a right atrial appendage-ventricular connection using a percutaneous epicardial approach, after repeated failure of endocardial ablation attempts.
