Investigation of the Adagio Cryoablation System in Patients With Atrial Fibrillation

The objective of the study is to demonstrate the safety and feasibility of the Adagio Cryoablation System is subjects with Paroxysmal (PAF), Persistent (PsAF) and Long-Standing Persistent Atrial Fibrillation.

Phase N/A

Transcutaneous Electrical Vagus Nerve Stimulation to Suppress Atrial Fibrillation

Atrial fibrillation (AF) is the most common cardiac arrhythmia. In previous experimental studies, the investigators found that low-level vagus nerve (VN) stimulation (LLVNS), at voltages substantially below that which slowed the sinus rate, significantly suppressed AF inducibility and decreased AF duration. The investigators subsequently developed a non-invasive neuromodulatory therapy, in ...

Phase N/A

Comparison of Circumferential Pulmonary Vein Isolation Alone Versus Linear Ablation in Addition to Circumferential Pulmonary Vein Isolation for Catheter Ablation in Persistent Atrial Fibrillation: Prospective Randomized Controlled Trial

The purpose of this study is to compare the clinical outcomes depending on catheter ablation strategy for persistent atrial fibrillation. After randomization, investigators will conduct circumferential pulmonary vein isolation alone in a group, and additional posterior box isolation and anterior linear ablation in the other group. Investigators will compare clinical ...

Phase N/A

Dabigatran Versus Conventional Treatment for Prevention of Silent Cerebral Infarct in Atrial Fibrillation Associated With Valvular Disease

Amongst different types of cardiac arrhythmia, tachyarrhythmia shows the highest prevalence. The prevalence of AF, which is tachyarrhythmia, is approximately 2% of the entire population and 5% of the population at the age of 60 or older. AF is the cause of approximately 20% of all events of ischemic stroke, ...

Efficacy of Delayed Enhancement MRI-Guided Ablation vs Conventional Catheter Ablation of Atrial Fibrillation

BACKGROUND AND INTRODUCTION: Atrial fibrillation (AF) is the most common cardiac arrhythmia affecting millions of people in the US and around the world. Treating AF continues to be a challenge. Over the last 15 years, catheter based AF ablation procedure has been widely adopted. Approximately 50% of patients treated with ...

Phase N/A

Correlation of the Arrhythmia Mechanism and Substrate to Ablate Persistent Atrial Fibrillation Study

Pulmonary vein isolation catheter ablation for the treatment of persistent AF (PeAF)or longstanding persistent AF is associated with success rates of 40-50% at one year. Experimental models have shown that AF results in progressive structural changes due to electrical atrial remodeling, where AF burden correlates with atrial fibrosis. The optimal ...

Phase N/A

Evaluation of Conventional Ablation With or Without Focal Impulse and Rotor Modulation to Eliminate Human AF

Atrial fibrillation (AF) affects over 2 millions Americans. AF may reduce cardiac performance and may result in thrombus formation in the left atrium and thromboembolic events, such as stroke. Ablation to eliminate the causes of this arrhythmia is increasingly performed since pharmacological therapy is suboptimal. Ablation currently targets triggers, by ...

Phase N/A

Wide Area Circular Ablation Versus Extra-wide Area Circular Ablation in Persistent Atrial Fibrillation

Ablation of atrial fibrillation is an established method for treatment of subjects with atrial fibrillation with goal of restoration of sinus rhythm. Among different methods, wide area circular ablation (WACA) is shown to provide the same results with fewer complications. This project will compare WACA with extra-wide area circular ablation ...

Phase N/A

Impact of Anticoagulation Therapy on the Cognitive Decline and Dementia in Patients With Non-Valvular Atrial Fibrillation

Patients will be screened at Intermountain Medical Center and at Intermountain-affiliated anticoagulation clinics in the Salt Lake City region. Patients with non-valvular atrial fibrillation will be considered for study. After written informed consent is obtained, subjects who meet eligibility criteria will be randomized 1:1 to 2 treatment arms: Group 1: ...

Phase

Apixaban for the Reduction of Thrombo-Embolism in Patients With Device-Detected Sub-Clinical Atrial Fibrillation

Device-detected sub-clinical atrial fibrillation (SCAF) is a new disorder that has been recognized since the availability of implantable devices capable of long term continuous heart rhythm monitoring. It is characterized by one or more runs of rapid atrial arrhythmia detected by the device without symptoms and without any clinical atrial ...
