U.S., Jan. 10 -- ClinicalTrials.gov registry received information related to the study (NCT07330791) titled 'Right Phrenic Nerve Localization on CT for Ablation' on Dec. 10, 2025.
Brief Summary: The anatomical location of the right phrenic nerve (RPN) in close proximity to the right pulmonary veins has become a critical consideration for electrophysiologists performing pulmonary vein isolation, the cornerstone treatment for atrial fibrillation. Although radiofrequency ablation in this region is rarely associated with complications-unlike cryoballoon ablation-the proximity of the RPN to the ablation site is considered the most widely accepted mechanism of nerve injury. Therefore, accurately defining its anatomical course is essential to pre...
