(FIT)-Module 6 Lectures: Special Technology Sessions-Electroanatomic Mapping

Video Transcription

Video Summary

In his presentation, John Miller from the Heart Rhythm Society delves into the nuances of electroanatomic mapping in electrophysiology, focusing on the BioSense Carto system, although the principles can apply generally. Electroanatomic mapping offers numerous applications, including anatomical referencing within the heart, activation mapping, and image mapping to identify scar tissue and healthy tissue. It assists with catheter manipulation for safe ablation planning and designating target sites.<br /><br />Miller underscores the essential practices for effective use of electroanatomic mapping. He emphasizes the importance of setting up the system correctly, choosing stable references, picking the right activation window, and ensuring good catheter-tissue contact. Additionally, delineating the complete chamber of interest and watching for any tachycardia changes during procedures are crucial.<br /><br />Despite the revolutionizing impact of mapping systems on ablation practices, enhancing safety and efficacy, these technologies do not replace the clinician's expertise. They can potentially mislead without proper oversight. Therefore, practitioners must carefully manage how they interpret mapping data, especially in terms of activation times and voltage maps.<br /><br />Miller urges caution against over-reliance on the technology, noting that it cannot independently diagnose tachycardias, guarantee efficacy in treatment, nor eliminate complications. Future advancements might ease some of these challenges, with improvements in reference assignment automation, high-density mapping capabilities, and enhanced algorithms for annotation and data accuracy. The presentation advocates leveraging these technologies while maintaining vigilant clinical judgment and oversight.
