Anticoagulation in ICH Survivors for Stroke Prevention and Recovery
open to eligible people ages 18 years and up
Primary Aim: To determine if apixaban is superior to aspirin for prevention of the composite outcome of any stroke (hemorrhagic or ischemic) or death from any cause in patients with recent ICH and atrial fibrillation (AF). Secondary Aim: To determine if apixaban, compared with aspirin, results in better functional outcomes as measured by the modified Rankin Scale.

aMAZE Study: LAA Ligation Adjunctive to PVI for Persistent or Longstanding Persistent Atrial Fibrillation
Sorry, in progress, not accepting new patients
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. (COMPLETED) All subjects from both stages will be included in the primary analysis.

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.

Health eHeart BEAT-AFib - Health eHeart Biomarkers of Early Atrial Transformation in Atrial Fibrillation
Sorry, not yet accepting patients
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.

Individualized Studies of Triggers of Paroxysmal Atrial Fibrillation
Sorry, in progress, not accepting new 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.

Randomized Endo-Vein Graft Prospective
Sorry, in progress, not accepting new patients
Coronary artery bypass grafting (CABG) is the most common major surgical procedure in the United States with over 300,000 cases performed each year. To restore blood flow to the heart, vascular conduits from another part of the body are procured to create a bypass around critically blocked coronary arteries. The left internal thoracic artery is the conduit of choice for CABG due to its superior long-term patency. However, almost all patients referred for CABG require additional grafts to provide complete revascularization. This necessitates the harvest of other vessels, most commonly the saphenous vein which is used almost ubiquitously in contemporary CABG with an average of two vein grafts per CABG procedure. In the last 10 years, Endoscopic Vein Harvesting (EVH) has been recommended as the preferred method over the traditional open harvesting technique (OVH) because it provides a minimally invasive approach. However, more recent investigations indicate potential for reduced long-term bypass graft patency and worse clinical outcomes with EVH. The long term impact of EVH on clinical outcomes has never been investigated on a large scale using a definitive, adequately powered, prospective Randomized Controlled Trial (RCT) with long-term follow-up.

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.
The HOLIDAY (HOw ALcohol InDuces Atrial TachYarrhythmias) Study
Sorry, in progress, not accepting new patients
Atrial fibrillation (AF) is the most common sustained arrhythmia in the United States and it has been associated with ethanol use. Understanding how ethanol affects the electrical properties of the heart and induces AF has important public health implications. The objective of this research is to investigate the mechanistic relationship between ethanol and atrial fibrillation in humans by performing a placebo controlled study looking at the electrical properties of the heart in patients receiving intravenous ethanol or placebo. The investigators hypothesize that ethanol increases the susceptibility of human myocardium to atrial fibrillation through electrophysiologic changes in the atrial myocardium in the acute setting.
