Core Concepts in EP Topics: The Tetralogy of Fallot-CardiResynchronization and Right Ventricular Resynchronization

CardiResynchronization and Right Ventricular Resynchronization - Dubin

Video Transcription

Video Summary

The video by Anne Dubin from Stanford University discusses cardiac resynchronization in Tetralogy of Fallot patients with right bundle branch block. The Tetralogy includes a malaligned VSD causing pulmonary issues, often leading to right bundle branch block. Resynchronization therapy shows improved outcomes, prompting a question of whether these patients should receive resynchronization and if biventricular treatment is necessary. Studies explored acute and chronic responses to RV pacing, with findings of improved cardiac function and decreased QRS duration. Further research on biventricular pacing showed initial improvement in LV function and overall survival. Conduction system pacing emerged as a less invasive alternative with similar benefits. In conclusion, Tetralogy patients have varying dyssynchrony patterns benefitting from resynchronization therapies, including potential advances in conduction system pacing.
