| Research Abstract |
To test if prophylactic pulmonary vein isolation prevents development of atrial fibrillation, the left atrial antrum circular ablation was performed by a bipolar radiofrequency ablation device in a subclavian artery - pulmonary artery canine model. The left atrial dimension was progressively increased. The atrial activation cycles were progressively shortened, particularly in the left atrium. During atrial fibrillation, focal rapid activations were observed at the superior pulmonary veins. These activations were blocked by the pulmonary vein isolation.
