EP Fellows Curriculum: Electro-anatomical Considerations for the Catheter Ablation of Accessory Pathways

Video Transcription

Video Summary

In this lecture, the speaker discusses the importance of understanding the electroanatomy of accessory pathways for successful catheter ablation. They explain that when mapping and ablating accessory pathways, it is crucial to consider appearance, location, and timing. By analyzing these factors, EPs can accurately identify the location of the pathway and target it for ablation. The speaker emphasizes that fusion does not necessarily indicate the best place to ablate and that timing is always relative. They also discuss the complex anatomy of the annulus, including the variability and topography of different regions. The speaker provides examples and case studies of mapping and ablating accessory pathways, highlighting the importance of mapping all areas thoroughly and being willing to change the AV ratio for successful ablation. They also discuss the paraseptal space and how to effectively map and ablate pathways in this region. The speaker concludes by reminding EPs to consider the specific electroanatomic characteristics of each patient's pathway and adjust their approach accordingly.
