INTRODUCTION Though pulmonary vein (PV) isolation has been widely adopted for treatment of atrial fibrillation (AF), recurrence rates remain unacceptably high with persistent and longstanding AF. As evidence emerges for non-PV substrate changes in the pathogenesis of AF, more extensive ablation strategies need further study. METHODS We modified our PV antrum isolation procedure to include abatement of posterior and septal wall potentials. We also employed recently described image-processing… CONTINUE READING
