  • A Novel Healthcare Information Technology Tool to Improve Care in Patients With Atrial Fibrillation

    open to eligible people ages 18 years and up

    Patients with implantable heart devices including pacemakers, defibrillators, and cardiac monitors may not seek regular medical care related to their implanted devices. These devices are capable of detecting abnormal heart rhythms or other device abnormalities that may benefit from clinical action or oversight. A novel healthcare information technology has been developed and is being implemented clinically for screening of patients with cardiac rhythm devices who seek care in the emergency room setting. This study seeks to examine differences in detection of cardiac rhythm disturbances including atrial fibrillation (AF) with utilization of this new screening technology, and how often treatment plans change in patients who have a heart rhythm abnormality detected.

  • AntiCoagulation Tracking InterVention and Evaluation

    Sorry, not yet accepting patients

    Anticoagulants are a leading cause of acute injury from adverse drug events, leading to ~20,000 serious injuries reported to the Food and Drug Administration per year and more than 220,000 emergency department visits annually. Therefore, we propose to implement a health information technology (HIT) population management tool at two distinct anticoagulation clinics that will allow the care team to assign and track tasks essential for timely patient monitoring. We will examine its effect on anticoagulation management outcomes through a randomized trial, hypothesizing that such interventions can be effective as well as cost-effective strategies to improve patient safety in the context of anticoagulation management services.

  • Edoxaban Compared to Standard Care After Heart Valve Replacement Using a Catheter in Patients With Atrial Fibrillation (ENVISAGE-TAVI AF)

    Sorry, in progress, not accepting new patients

    When the upper chambers of a person's heart receive irregular electrical signals it causes abnormal rhythm in the heart beat. This is called atrial fibrillation. Atrial fibrillation increases the chance of having a heart attack or stroke. Some patients also get new heart valves using a catheter. Often doctors give patients a medicine called a vitamin K antagonist (VKA), because it is considered the standard care. This study will see how edoxaban compares to VKA in patients who got a new heart valve by using a catheter. The study will compare the two drugs for up to three years after heart valve replacement, looking at the drug's overall side effects (called adverse events) and major bleeding.

  • Effectiveness Study of Circumferential vs. Segmental Ablation in Paroxysmal Atrial Fibrillation

    Sorry, in progress, not accepting new patients

    This is a PI-initiated study that aims to evaluate the efficacy of two different methods of paroxysmal atrial fibrillation (PAF) ablation. There are currently two strategies for PAF ablation that are routinely performed by electrophysiology clinicians: (1) circumferential pulmonary vein ablation (CPVA) and (2) segmental pulmonary vein isolation (SPVI). However, it is not known if one approach is better than the other. This randomized study will evaluate and compare the efficacy of CPVA versus SPVI in subjects undergoing ablation for paroxysmal atrial fibrillation only. Subjects will have a 50/50 chance of receiving either the CPVA or SPVI ablation method.

  • Health eHeart BEAT-AFib - Health eHeart Biomarkers of Early Atrial Transformation in Atrial Fibrillation

    Sorry, accepting new patients by invitation only

    Atrial fibrillation (also known as AFib or AF) is the most common abnormal heart rhythm and results in an irregular beating of the heart. Currently, there is no way of identifying patients at most risk for the development or progression of AFib or those that will best respond to treatment. The purpose of this study is to improve our understanding of AFib and to find new ways of identifying those patients most at risk for developing AFib, have progressive AFib or be less responsive to treatment. For this reason, the investigators are studying imaging, blood, and digital markers that may contribute to AFib Subjects will receive mobile devices (such as an AliveCor or similar device) for remote electrocardiographic (ECG) monitoring. Additionally, subjects will use features using a smartphone research app (on the Eureka Research Platform) to monitor other important things such as activity, sleep, heart rate and others as they are developed. All subjects will receive serial blood draws and saliva sample collections once a year. Subjects will also undergo annual imaging in the form of an echocardiogram (Echo). Evaluations will be taken at baseline and once a year for three years from the baseline visit. Additionally, electronic surveys will be administered periodically (eVisits occurring every 3-6 months) using the mobile app.

  • Left Atrial Posterior Wall and PV Isolation Using Cryoballoon for Treatment of Persistent AF

    Sorry, not yet accepting patients

    The purpose of this study it to learn whether pulmonary vein isolation (PVI) along with isolation of the posterior left atrial wall (PWI) in the region of the pulmonary venous component will reduce the likelihood of atrial fibrillation (AF) recurrence in patients with persistent atrial fibrillation at 12 months, after a single ablation procedure, in comparison to PVI alone. The investigator hypothesizes that the combination of PVI + PWI will result in a significant reduction in recurrence of atrial fibrillation at 12 months after ablation.

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

    Sorry, in progress, not accepting new patients

    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.

  • Subxyphoid Hybrid MAZE Registry for Patients With Persistent Atrial Fibrillation

    Sorry, accepting new patients by invitation only

    Minimally invasive surgical procedures have been advocated as an alternative to catheter ablation for the treatment of persistent atrial fibrillation. Initial results have been promising in maintaining sinus rhythm compared to catheter ablation, but are associated with a considerably greater number of procedural-related adverse events compared to catheter ablation. This study investigates the safety and feasibility of a new subxyphoid epicardial/endocardial hybrid atrial fibrillation ablation and LAA exclusion approach for patients with persistent and longstanding persistent atrial fibrillation.

  • Transcutaneous (Tragus) Vagal Nerve Stimulation for Post-op Afib

    Sorry, not yet accepting patients

    Patients undergoing cardiac surgery are at high risk of developing atrial fibrillation (AF), with estimated rates of 30-50% and occurs at approximately 2-4 days after surgery. The autonomic nervous system is known to play a key role in AF. Animal studies have indicated that duration and inducibility of AF can be decreased with intermittent vagus nerve stimulation (VNS). In humans, literature suggests that transcutaneous (tragus) VNS (tVNS) can serve as a potentially non-invasive therapy for treatment of post-operative AF (POAF) by reducing inflammation and increasing atrial refractory period. The purpose of this study is to determine the value of tVNS in reducing the burden of POAF and days of hospitalization after cardiac surgery.
