Pharmacogenetic Study of Antiarrhythmic Drugs for Atrial Fibrillation

1.0 Background While atrial fibrillation (AF) is the most common sustained cardiac arrhythmia requiring therapy, it is also associated with increased risk of stroke, heart failure, myocardial infarction, dementia, and death. The number of Americans affected with AF is expected to surge to nearly 16 million by the year 2050. ...

Left Atrial Appendage Occlusion Guided by 3D Printing

The 3D printing has modified the LAAC practices with a preoperative time allowing an optimal preparation of the prosthesis. This technique is now used in several surgical centers and prospective evaluation of the practice is necessary. The objective of our research is to demonstrate the reduction of the operating time ...

Phase N/A

Multimodality Prediction of Success of Atrial Fibrillation Rhythm Control Strategy

In this study the investigators aim to build a model to predict the maintenance of sinus rhythm (SR) after successful direct current cardioversion (DCC) incorporating standard predictors such as echocardiographic parameters, clinical parameter and 12-lead ECG parameters and new parameters, including 17-lead ECG, Oesophageal-ECG and single nucleotide polymorphisms (SNPs). Using ...

Phase N/A

Frontal Cognitive Control Functions Before and After Percutaneous Catheter Procedures in Treatment of Atrial Fibrillation

Atrial fibrillation is a common arrythmia. It is an independent risk factor for stroke. There for anticoagulation therapy is used for atrial fibrillation patients. Alternatively, left atrial appendix closure can be used, if the risk for bleeding complications is deemed greater than the possible antithrombotic benefit of anticoagulation medication. Up ...

Phase N/A

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: ...
