COMParison of Algorithms for Rotational Evaluation in Atrial Fibrillation

In this study, the investigators will analyze electrograms collected routinely at clinical electrophysiology study (EPS) in patients undergoing ablation for atrial fibrillation. These electrograms will be recorded from a variety of clinically approved catheters under standard of care conditions, and will be analyzed to better understand the mechanisms for atrial ...

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

Esophageal 3D Mapping System for Cardiac Arrhythmias

Background Cardiac arrhythmias are common and may have devastating consequences for affected patients. To prevent f.e. strokes due to atrial fibrillation, heart failures as a consequence of long-standing tachyarrhythmias or death due to ventricular fibrillation, accurate and timely diagnoses are essential. The standard diagnostic tool for heart rhythm disorders in ...

Phase N/A

PV Reconnection After PVAI at Different Power Settings and Adenosine Provocation

Background The efficiency of catheter ablation in drug-refractory atrial fibrillation (AF) is compromised by high incidence of post-ablation AF recurrences requiring multiple ablation procedures (1). Post-PVAI (pulmonary vein antrum isolation) AF recurrence is mostly due to reconnection of the previously isolated PVs (2). Earlier studies have revealed that elimination of ...

Phase

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

Autoimmunity in the Pathogenesis of AF

The study sets out to identify an explanation for the pathogenesis of AF, potentially forming the basis for designing novel targeted therapies to prevent or reverse this prevalent human disease. The overall objectives are to determine whether autoimmune diseases are associated with AF development and to identify specific diagnostic and ...

Phase N/A

A Pilot Study on Edoxaban for the Resolution of Left Atrial Thrombosis in Patients With Non-valvular Atrial Fibrillation

This is a non-controlled, open-label, 4 weeks pilot study. As the main goal of this exploratory study is the estimation of the magnitude of the Left Atrial /Left Atrial Appendage thrombus resolution with edoxaban, no control group with vitamin K antagonists has been considered, providing that, for the purpose of ...

Phase

Tragus Stimulation to Prevent Atrial Fibrillation After Cardiac Surgery

This is a single-blind study where patients will be randomized tragus stimulation versus sham procedure and remain blinded to their treatment allocation. Both treatment options will utilize similar equipment, namely the use of alligator clips which will be placed on the tragus and earlobe of the right ear for patients. ...

Phase N/A

Assessment of the Link Between Monomeric Functional Form Plasma Level of Vasostatin-1 and Occurrence of New Onset Atrial Fibrillation in Severe Intensive Care Patients

Atrial fibrillation (AF) is a cardiac rhythm disorder particularly common in intensive care patients. Some meta-analyzes report a prevalence of new onset AF ranging from 4.5% to 29.5% in polyvalent intensive care. In our department, a recent month-long survey showed that more than 30% of the patients who were unhealthy ...
