New treatment option for Atrial Fibrillation
Official title The CONFORM Pivotal Trial
ClinicalTrials.gov ID: NCT05147792
What this study is testing
- What it's testing
- The CLAAS® device will be evaluated for safety and efficacy by establishing its performance is non-inferior to the commercially available WATCHMAN® and Amulet™ left atrial appendage closure devices in patients with non-valvular atrial fibrillation. Patients who are eligible for the trial will be randomized to receive either the CLAAS device or the WATCHMAN or Amulet™ devices and will be followed for 5 years after device implant.
