Atrial Fibrillation clinical trials at UCSF
4 in progress, 2 open to new patients

  • aMAZE Study: LAA Ligation Adjunctive to PVI for Persistent or Longstanding Persistent Atrial Fibrillation

    open to eligible people ages 18–80

    This study is a prospective, multicenter, randomized (2:1) controlled study to evaluate the safety and effectiveness of the LARIAT System to percutaneously isolate and ligate the Left Atrial Appendage from the left atrium as an adjunct to planned pulmonary vein isolation (PVI) catheter ablation in the treatment of subjects with symptomatic persistent or longstanding persistent atrial fibrillation. This study will be conducted in two stages: - Limited Early Stage (Stage 1): up to 250 subjects at up to 65 sites. (COMPLETED, transitioned to Stage 2) - Pivotal Stage/ Phase III (Stage 2): up to 600 subjects at up to 65 sites. (ENROLLING) All subjects from both stages will be included in the primary analysis.

  • Rate of Atrial Fibrillation Through 12 Months in Patients With Recent Ischemic Stroke of Presumed Known Origin

    open to eligible people ages 50 years and up

    The purpose of the Stroke AF study is to compare the incidence of atrial fibrillation (AF) through 12 months between continuous cardiac rhythm monitoring with the Reveal LINQ™ Insertable Cardiac Monitor (ICM) (continuous monitoring arm) and standard of care (SoC) medical treatment (control arm) in subjects with a recent ischemic stroke of presumed known origin.

  • Individualized Studies of Triggers of Paroxysmal Atrial Fibrillation

    Sorry, not yet accepting patients

    The I-STOP-Afib study will test the comparative effectiveness of using N-of-1 trials vs. symptom surveillance alone to reduce Atrial Fibrillation (AF) episode frequency and severity and improve quality of life for AF patients. The study will involve randomizing almost 500 paroxysmal AF patients to either AF episode tracking versus engaging in testing the relationship between participant-selected triggers and AF episodes utilizing a mobile-app based N-of-1 study design. Both groups will complete a validated survey to assess AF severity, essentially a measure of quality of life while living with AF, before and after a 3 month testing period.

  • Catheter Ablation vs Anti-arrhythmic Drug Therapy for Atrial Fibrillation Trial

    Sorry, in progress, not accepting new patients

    The (Catheter Ablation Versus Anti-arrhythmic Drug Therapy for Atrial Fibrillation Trial) CABANA Trial has the overall goal of establishing the appropriate roles for medical and ablative intervention for atrial fibrillation (AF). The CABANA Trial is designed to test the hypothesis that the treatment strategy of left atrial catheter ablation for the purpose of eliminating atrial fibrillation (AF) will be superior to current state-of-the-art therapy with either rate control or rhythm control drugs for decreasing the incidence of the composite endpoint of total mortality, disabling stroke, serious bleeding, or cardiac arrest in patients with untreated or incompletely treated AF.
