Abstract:
Pulmonary vein isolation (PVI) is the only proven ablation strategy for paroxysmal and persistent atrial fibrillation (AF). However, when AF recurs despite durable PVI in a subgroup of patients with persistent AF, there is no scientifically proven ablation strategy to pursue. Here, we summarized how we approach persistent AF at Johns Hopkins Hospital.
