(FIT)-Module 3 Workshop 5: Invasive and Non-Invasive Correlation-Marchlinski Case 4 Answer

Video Transcription

Video Summary

The discussion focuses on assessing whether signals indicate true reconnection of the pulmonary veins or are merely far field atrial signals. The initial analysis suggests no reconnection; however, confirmation requires additional maneuvers such as pacing from the vein and manipulating the catheter deeper into the vein. While pacing inside the vein has not shown capture, suggesting far field signals, further testing from different left atrium sites is needed to confirm. The right pulmonary vein appears isolated, while the situation with the left vein remains inconclusive, necessitating further evaluation to ensure that no true vein reconnection is present.
