How To Achieve Durable Pulmonary Vein Antral Isolation?

ABSTRACT

The inability to achieve durable pulmonary vein isolation(PVI) remains a major limitation to a catheter ablation for thew treatment of atrial fibrillation(AF), potentially resulting in AF recurrence.In this review,we discuss the research performed investigating methods to improve lesion permanence for the goal of durable PVI.Investigations evaluted procedural techniques,various catheres utilized, adjunctive pharamacologic therapy and novel energy sources designed to improve ablation lesion permanence are discussed.
