(FIT)-Module 2 Workshop 3: SVT Mechanisms and Maneuvers-Miles Case 5 Question

Video Transcription

Video Summary

The video discusses the mapping of a mid-septal accessory pathway for RF ablation. It evaluates potential ablation strategies, suggesting starting at high powers for a durable lesion and delivering energy during ventricular pacing. The site, located in Cope's Triangle, is considered reasonable for ablation. Techniques like high-frequency, low tidal volume ventilation or breath holding might be useful. It is noted that QRS widening during RF energy delivery often indicates successful pathway disruption. The ablation site is midway between the coronary sinus os and the His bundle, emphasizing a strategic positioning for effective treatment.
