About

This study is a prospective, non-randomized, single arm, multicenter, CE marking trial for patients with paroxysmal atrial fibrillation to undergo an ablation of the cardiac tissue near the PV.

Full description

The objective of this clinical investigation is to confirm the safety and performance of the Vimecon® Laser Cardiac Ablation Instrument when creating scar tissue within the cardiac wall for the treatment of atrial fibrillation.

Up to 66 patients with paroxysmal atrial fibrillation refractory to at least one antiarrhythmic medications (Class I or III) are enrolled. with an expected 10% dropout; 59 per protocol patients are required.

The study duration will be 18 month with a 6 month enrollment period and 12 month follow-up. Interim follow-up visits are at post procedure, 1 Month, 3 Months, 6 Months and 12 Months.

The baseline and follow up tests are standard of care. Additional optional tests are an esophageal endoscopy for determination of potential fistula formation and a cerebral MRI for micro embolism post treatment.

  11. TIA or stroke within the last 6 months
  12. Pregnant and breastfeeding Women
  13. Previous relevant cardiac surgery (e.g. ASD, PFO, Maze, AICD, pacemaker, congenital heart disorders or valve replacement).
  14. Previous ablation of the pulmonary vein.
  15. Known or suspected atrial myoma
  16. Subject has co-morbid conditions that place the subject at an unacceptable risk (e.g., severe chronic obstructive pulmonary disease, hepatic failure, cerebral degenerative diseases, immunosuppressive abnormalities, hypercoagulable state, nervous system disease and hematological abnormalities.)
  17. Contraindicated for the protocol defined anticoagulation plan (per ACC/AHA//ESC Practice Guidelines)
  18. Patients with known allergic reactions to the local anesthetic, sedatives, x-ray dye, heparin, protamine, components of the catheter (platinum, iridium, stainless steel) or other agents administered during the procedure.
  19. AV-Block IIº and IIIº
  20. Contraindication for femoral vein and pulmonary veins access (e.g.: femoral Stent graft, excessive calcification, previous surgical interventions in or adjacent to the femoral veins that impede femoral access)

  22. MI in the last 3 months.
  23. Enrolled in another clinical trial with a non-CE marked device which has not yet reached its primary endpoint
