(FIT)-Module 4 Workshop 6: Electrocardiographic and Electrophysiological Correlations-Gerstenfeld Case 4 Answer

Video Transcription

Video Summary

For treating certain cardiac conditions, ablating in the left cusp is often effective. When early at the AIV, you're limited by power, and directly aligning LEDs poses high risks. Switching to cryoablation might not reach effectively. If the AVR-AVL Q-wave ratio is less than 1.5, it indicates potential success in the left cusp, aligning with a study by Bullock from the Penn Group. Ablating near coronaries, even at low power, is not advisable, and cryoablation isn't ideal. For patients with PBC and dyschromatopathy, flecainide may be unsuitable. Therefore, left cusp ablation remains the best option.
