(FIT)-Module 2 Lectures: Invasive Diagnosis and Treatment Part 1-Catheter Ablation of AV Nodal Reentry (Miles)

Video Transcription

Video Summary

In this presentation, Professor Bill Miles of the University of Florida discusses the catheter ablation of atrioventricular nodal reentrant tachycardia (AVNRT). He explains the condition as involving two distinct pathways, the fast and slow AV nodal pathways, and elaborates on the three types: slow-fast, fast-slow, and slow-slow AV node reentry. The talk details the anatomy of the AV node and related pathways, diagnostic techniques, and strategies for effective treatment through catheter ablation.<br /><br />The presentation emphasizes the importance of accurate diagnosis, excluding other types of arrhythmias, and details the ablation procedure typically performed in sinus rhythm using both electrogram and anatomic criteria. The potential risks, such as AV block, are discussed alongside strategies to mitigate them, such as cryoablation and the use of electric mapping. Miles also advises close monitoring for junctional rhythms during procedures and offers management strategies for atypical cases where fast pathways are not involved. Overall, the lecture provides a comprehensive overview for medical professionals managing AVNRT.
