High-resolution MRI of Atrial Fibrillation Patients Prior to Focal Impulse and Rotor Modulation (FIRM) Ablation
Patients undergoing FIRM guided ablation of atrial fibrillation will undergo high resolution MRI imaging to determine correlation of underlying anatomic fibrotic regions with FIRM targeted sites for ablation.
The CoAGulation Biomarkers and Atrial Fibrillation (COAG-AF) Pilot Study
The aim of the Correlation Of CoAGulation-Atrial Fibrillation (COAG-AF) study is to prove that an increase in pro-thrombotic biomarkers in AF is associated with an increase in AF burden. Secondary objectives of the study are the following: To investigate the impact of catheter ablation on serum pro-thrombotic biomarkers in patients …
Machine Learning in Atrial Fibrillation
Atrial fibrillation is a serious public health issue that affects over 5 million Americans (Miyazaka, Circulation 2006) in whom it may cause skipped beats, dizziness, stroke and even death. Therapy for AF is currently suboptimal, in part because AF represents several disease states of which few have been delineated or …
Implantable Cardiac Monitor to Detect Atrial Fibrillation in Patients With MINOCA
Myocardial infarction with non-obstructive coronary arteries (MINOCA) (i.e.<50% stenoses) on coronary angiography) is an underappreciated clinical entity concerning 5-6% of patients with acute myocardial infarction. Approximately 50% of these patients remain without appropriate diagnosis and treatment. The MINOCA study aims at systematically assessing the frequency of underlying pathologies of MINOCA …
The Role of hs Troponin I and NT-proBNP in Predicting Atrial Fibrillation in Patients With Permanent Pacemakers
The goal of this clinical trial is to answer the research question whether hs Troponin I and NT-proBNP have a role in detecting atrial fibrillation in patients with pacemakers. Objectives of the study: To survey some risk factors for atrial fibrillation in patients with permanent pacemakers. To determine the role …
Comparison of Different Ablation Surgeries on Left Atrial Reverse Remodeling in Patients With Atrial Fibrillation
The goal of this Ambispective cohort Study is to compare in patients with paroxysmal atrial fibrillation undergo pulse field ablation and radiofrequency ablation, respectively. The main question it aims to answer are:Comparison of the therapeutic effects of pulse field ablation and traditional thermal ablation on patients with paroxysmal atrial fibrillation …
Mechanisms of Myocardial Injury and Ischemia in Patients With Rapid Atrial Fibrillation
The goal of this observational study is to better understand the role of measuring troponin (a protein measured by a blood test) and coronary imaging in patients presenting with rapid atrial fibrillation (AF) The main questions this study aims to answer are: Are patients with a fast, irregular heartbeat (rapid …
Post-marketing Clinical Study of the LAMBRE System for Left Auricle Closure
Atrial fibrillation (AF) is responsible for 15-20% of ischaemic strokes. These events are often caused by thrombus formation in the left atrium. Thromboembolic risk in AF is primarily prevented by oral anticoagulation. However, this drug-based approach has a number of limitations, the most important of which are compliance problems and, …
Heart Rate Variability After Ablation
Pulsed-field catheter ablation is a promising new treatment method for patients with atrial fibrillation. The mechanism of cell damage here is different from that of classic catheter ablation, in which the ganglion plexuses around the pulmonary veins are also damaged and thus changes in the autonomic nervous system occur. The …
Clinical and Healthcare Outcomes From Real-World Use in the United States of a Companion AI During AF Ablation
Observational, multi-center, clinical device registry for US patients with a primary goal to observe the clinical outcomes in patients who are mapped with Volta Medical's VX1 or AF-Explorer systems during AF ablation procedures.
