Mapping Atrial Fibrillation in 2020: Key Updates, Emerging Techniques, Unresolved Issues-Global Contact Mapping

Video Transcription

Video Summary

The speaker discusses the use of global contact mapping for atrial fibrillation. They explain that mapping techniques have evolved from a general concept to more specific approaches, aiming to identify specific targets for ablation to improve outcomes. The speaker highlights the clinical evidence from a multi-center trial, which showed that the addition of contact mapping to pulmonary vein isolation (PVI) improved one-year freedom from atrial fibrillation and atrial tachycardia in patients with persistent and long-standing persistent AF. However, they note that further research is needed to understand the optimal mapping techniques and ablation approaches, as well as address the variability in results between different centers. The speaker also explores the potential of mapping drivers of atrial fibrillation and the challenges in interpreting electrical indices and finding dominant sites. They conclude that contact mapping is a promising method, but further improvements and standardization are needed for its widespread use.
