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

Video Transcription

Video Summary

The video discusses the ablation of accessory pathways in the heart using electroanatomic mapping. When a pathway is bumped and conduction is temporarily blocked by catheter trauma, ablation should be pursued since this indicates a good location. This approach mitigates concerns about AV block risks, as they are minimal at the site. The mapping is crucial for identifying the precise area for ablation even if pathway conduction initially ceases. Eventually, it typically recovers, and the ablation process can continue. Electroanatomic mapping also aids in catheter positioning without the need for fluoroscopy.
