      Renal Denervation + PVI vs PVI Alone for Persistent AF
      Recruiting
                          New Jersey
        This study is looking to determine if patients with persistent AF with controlled hypertension or without hypertension who are referred for catheter ablation (PVI) and undergo adjunctive RDN have reduced AF burden at 12 months in comparison to patients who undergo only PVI

    The Rhythm Evaluation for AntiCoagulaTion With Continuous Monitoring of Atrial Fibrillation
      Recruiting
                          Multiple Locations
        Are you an adult with atrial fibrillation? In this study, researchers are comparing a continuous direct oral anticoagulation (DOAC) use versus time-limited (1 month) DOAC guided by an AF-sensing Smart Watch (AFSW) for persons with atrial fibrillation and a moderate risk of stroke. Participants must be between the ages of 22 and 85 and have a history of atrial fibrillation. The study is taking place at locations in California, Colorado, Florida, Georgia, Illinois, Indiana, Iowa, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Jersey, New Mexico, New York, North Carolina, Ohio, Oklahoma, Pennsylvania, South Carolina, Texas, Virginia, Wisconsin, and Washington, D.C.

    Gene Therapy for Post-Operative Atrial Fibrillation
      Recruiting
                          Massachusetts
        Are you at least 18 years old and have scheduled elective valve surgery? You may be able to participate in a study where researchers are investigating whether a type of gene therapy can help prevent a form of atrial fibrillation that occurs after surgery. The study is taking place in Worcester, Massachusetts.

    Sleep Apnea and Hypertrophic Cardiomyopathy (HCM)
      Recruiting
                          Minnesota
        Are you a Minnesota resident with hypertrophic cardiomyopathy?
                    This study aims to find out how common it is for people with hypertrophic cardiomyopathy to also have sleep apnea. Hypertrophic cardiomyopathy is a disease that causes the heart muscle to thicken. Participants will also wear a heart rhythm monitor to help researchers learn whether sleep apnea is linked to arrhythmia. The study seeks healthy volunteers as well as participants in the Hypertrophic Cardiomyopathy Registry. To participate in this study, you must not have had a catheter ablation procedure to treat atrial fibrillation, had surgery to replace your heart valves, or been treated for sleep apnea. The study is located in Rochester, Minnesota.

                          Massachusetts
              Texas
        Do you know someone who will be having heart surgery?
                    This study aims to identify what genetic patterns might cause atrial fibrillation and other adverse events that happen after heart surgery. To participate in this study, you must be between 20 and 90 years old. The study is in three locations in Massachusetts and Texas.

      Recruiting
                          Multiple Locations
        Did you develop atrial fibrillation after coronary artery bypass graft (CABG) surgery?
                    Did you develop atrial fibrillation after a coronary artery bypass grafting (CABG) surgery? This study is looking at how well oral anticoagulation medicines work to prevent complications, such as blood clots and heart attack, for patients who experience post-operative atrial fibrillation (POAF). This study is in multiple locations around the country.

      Recruiting
                          New York
        Are you an adult with atrial fibrillation who recently had a catheter ablation procedure? This study will investigate the effectiveness of an implantable cardiac monitor-guided device to monitor participants for recurrent atrial fibrillation following ablation. This study is located in Rochester, New York.
