SCAZZUSO, FERNANDO et al. El aislamiento de las venas pulmonares como tratamiento de la fibrilación auricular refractaria en un centro de Argentina. Rev.Urug.Cardiol. [online]. 2011, vol.26, n.2, pp.115-121. ISSN 1688-0420.

Between March 2009 and March 2011 we carried out 152 cases of pulmonary veins isolation (PVI), as treatment of the paroxysmal or persistent atrial fibrillation (AF). Our population was constituted mainly by men with an average age of 55,58 years old. The 81,9% of the population presented normal heart. Paroxysmal atrial fibrillation was present in 65,95% of the cases. Atrial fibrillation was present by an average of 7 years. All of them, had fulfilled a treatment with three different antiarrhythmic drugs none of them being beta blockers or calcium channel blockers. The number of episodes of AF was in average 6 per year. The rate of success during the procedure was 97,87%. The primary 12 months success rate was 88,32% for the group with normal heart and 64,08% for the group with cardiomyopathy. In our experience the isolation of the pulmonary veins is an attainable treatment in very select cases with an acceptable rate of success.
