Safety and Performance of a Pulsed Field Device for Global Mapping and Ablation of the Left Atrium for the Treatment of Atrial Fibrillation (PULSE-EU)

January 28, 2026 updated by: Kardium Inc.

PULSE-EU - A Prospective, Non-Randomized Clinical Pilot Study to Assess Safety and Performance of a Pulsed Field Device for Global Mapping and Ablation of the Left Atrium for the Treatment of Atrial Fibrillation

The purpose of this study is to provide clinical data pertaining to the safety and performance of the Globe Mapping and Pulsed Field Ablation System for treating subjects with atrial fibrillation (AF).

Description

Key Inclusion Criteria:

  1. Subjects planned for an AF catheter ablation procedure, with a documented history of AF.

    1. Diagnosis must be confirmed within 12 months before enrollment.
    2. (Repeat ablations) Patient had 1 previous PVI procedure with cryoablation, radiofrequency ablation or pulsed field ablation
  2. Subjects between 18 and 75 years of age, inclusive

Key Exclusion Criteria:

  1. Patients who have contraindications to open heart surgery
  2. Patients from an Intensive Care Unit
  3. Patients with active systemic infection (sepsis)
  4. Patients who have had previous ablation in the left or right atrium
  5. Patients who are post-heart transplant or who are awaiting cardiac transplantation or other cardiac surgery
  6. Patients with cardiac implants that may interfere with device delivery or positioning (e.g. atrial septal defect closure device, left atrial appendage occluder)
  7. Patients with mitral valve prolapse or other heart valve abnormalities excepting mild to moderate mitral regurgitation
  8. Patients with New York Heart Association Class III or IV heart failure
  9. History of a documented thromboembolic event, including stroke or transient ischemic attack (TIA)
  10. Bleeding disorder history
  11. Patients with a known sensitivity to anesthesia or neuromuscular block agent
  12. Currently undergoing long-term treatment with steroids, not including intermittent use of inhaled steroids for respiratory disease
  13. Myocardial infarction within the last three months
  14. Atrioventricular (AV) block II° or III°
  15. Left ventricular ejection fraction (LVEF) of less than 35%
  16. Unstable angina

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Globe Mapping and Pulsed Field Ablation System
Device: Globe Mapping and Pulsed Field Ablation System (Globe PF System)
During the procedure, the Globe Catheter will be delivered via standard femoral vein access and transseptal puncture. Anatomical and electrophysiological mapping of the left atrium (LA) will be followed by pulsed field ablation (PFA) to achieve pulmonary vein isolation (PVI). Additional PFA or radiofrequency (RF) ablation lesions may be created as deemed appropriate by the Investigator. Intracardiac electrogram mapping with the Globe PF System will be used to confirm PVI.
