Clinical Trial Summary

A prospective single-arm study of ganglionated plexi ablation in cardiothoracic surgery patients with a history of atrial fibrillation.


Description:

This study assesses the use of electroporation/pulsed field ablation (PFA) to selectively ablate ganglionated plexi in cardiothoracic surgery patients with atrial fibrillation. The PFA treatment will be performed in up to 12 patients with a history of paroxysmal atrial fibrillation. The primary end point will be recurrence of atrial fibrillation out to 1 year follow-ups.
