title: The Future of Pulmonary Vein Isolation - Single-shot Devices, Remote Navigation or Improving Conventional Radiofrequency Delivery by Contact Monitoring and Lesion Characterisation?
abstract: Pulmonary vein isolation is the main goal of atrial fibrillation (AF) ablation to date. Lack of isolation is associated with an increased risk of AF recurrences. Precise navigation to specific target sites, catheter stability and appropriate contact force are requisites for effective radiofrequency applications. Conventional manual-guided point-by-point radiofrequency energy delivery shows limitations to reach them, especially when performed by non-experienced electrophysiologists. New technological alternatives are rapidly arising and becoming clinically available to overcome some of the manual-guided radiofrequency delivery shortcomings. Here, we review the most recent clinical data, potential advantages, shortcomings and future directions of the new ablation strategies for pulmonary vein isolation.
