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

Video Transcription

Video Summary

In this presentation, Andrew Grace discusses the topic of non-contact mapping for atrial fibrillation. He explains that non-contact mapping has a long history in cardiology, beginning with the development of the electrocardiogram. Grace discusses the limitations of contact mapping systems and the need for non-contact mapping in order to improve outcomes in atrial fibrillation ablation procedures. He introduces a non-contact mapping tool called the CathoMAP, which uses ultrasound transducers and electrodes to record large amounts of data, including endocardial voltage samples. The key feature of this system is the calculation of charge density, which provides a more accurate and detailed map of the electrical activity in the heart compared to voltage-based mapping. Grace presents evidence of the efficacy and utility of non-contact mapping in detecting and treating atrial fibrillation, and concludes that this technology has the potential to significantly improve ablation approaches and patient outcomes.
