MARQUEZ, Manlio F e GOMEZ FLORES, Jorge. Evidence-based treatment of atrial fibrillation. Arch. Cardiol. Méx. [online]. 2006, vol.76, suppl.2, pp.204-208. ISSN 1665-1731.
Radiofrequency catheter ablation has emerged as a curative therapy for paroxysmal atrial fibrillation based on studies demonstrating the role of triggering foci in the pulmonary veins for the initiation of atrial fibrillation. Catheter ablation is performed by a trans-septal approach using radiofrequency energy at the ostium of each pulmonary vein. Mapping is guided by special catheters. Sequential radiofrequency applications eliminates or dissociates pulmonary vein muscle activity. Although complications exists, this procedure can be curative for these patients.
