Heart Conditions clinical trials at UCSF
11 in progress, 4 open to eligible people
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.

Does Eliminating Coffee Avoid Fibrillation?
open to eligible people ages 21 years and up
Given both the increasing population impact of atrial fibrillation (AF) and the widespread consumption of coffee in society, determining an associated benefit or risk of coffee consumption on AF is of great clinical relevance. This pilot study will evaluate the effect of randomly assigning participants undergoing electrical cardioversion to coffee abstinence or coffee consumption over a 12 month period. This pilot study will provide the first, randomized evaluation of coffee on AF outcomes and will provide important information on whether or not coffee has any effect on AF recurrence.

The FARAPULSE ADVENT PIVOTAL Trial
open to eligible people ages 18-75
This is a prospective, adaptive, multi-center, randomized safety and effectiveness pivotal study comparing the FARAPULSE Pulsed Field Ablation System with standard of care ablation with force-sensing RF catheters and cryoballoon catheters indicated for the treatment of PAF.

Wire Instrumentation Using Radiofrequency Energy to Impact Transseptal Efficiency
open to eligible people ages 18 years and up
This is a randomized controlled trial examining whether Baylis's Versacross RF wire versus the conventional Baylis RF needle is better at puncturing through a thin wall in the heart (called "transseptal puncture") as measured by time to successful transseptal puncture, during cardiac ablation procedures.

A Trial of High Power-Short Duration Versus Standard Power-Long Duration Radiofrequency Ablation for Treatment of Atrial Fibrillation
Sorry, in progress, not accepting new patients
This study is a prospective, randomized controlled study to compare overall clinical outcomes between High Power Short Duration (HPSD) and standard radiofrequency (RF) ablation settings for Atrial Fibrillation (AF) ablation in the treatment of subjects with paroxysmal or persistent Atrial Fibrillation.

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.

aMAZE Trial Continued Access Protocol
Sorry, in progress, not accepting new patients
aMAZE CAP is an extension to the current aMAZE Trial investigation (IDEG150107/NCT02517397/Protocol Appendix 16) in the form of a nested, non-randomized registry, to allow ongoing treatment of subjects and the collection of additional safety and effectiveness data at existing aMAZE investigational sites.

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.
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.

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.
