Resumen

SCAZZUSO, Fernando A et al. Pulmonary Vein Isolation for Treatment of Atrial FibrillationPulmonary Vein Isolation for Treatment of Atrial Fibrillation. Rev. argent. cardiol. [online]. 2012, vol.80, n.1, pp. 21-26. ISSN 1850-3748.

Between March 2009 and December 2010, 94 consecutive procedures of pulmonary vein isolation were performed for treatment of paroxysmal and persistent atrial fibrillation. These interventions constitute the initial experience of the Instituto Cardiovascular de Buenos Aires, where 260 procedures are currently performed each year. Our population consisted mainly of men with an average age of 55.58 years; 71.9% had no history of cardiovascular disease. Paroxysmal atrial fibrillation occurred in 65.3% of cases over an average of 7 years. All patients had received three different antiarrhythmic agents excluding beta blockers or calcium channel antagonists. The average number of episodes of atrial fibrillation was 6 per year. The success rate during the procedure was 97.87%. The primary success rate at 12 months was 84.04%, 88.32% for the group without heart disease and 64.8% for the group with heart disease. Mean follow-up was 18±6 months. In our experience, pulmonary vein isolation is a treatment strategy for very selective cases with an acceptable primary success rate.
