Clinical Study on the Effect of CPAP on AF Recurrence After Catheter Ablation in Patients with AF and OSA
Atrial fibrillation (AF) is the most common sustained arrhythmia in clinical practice, significantly increasing the risks of death, stroke, heart failure, cognitive impairment, and dementia, thus severely impacting patients' quality of life. However, for AF patients with concomitant cardiovascular risk factors, particularly those with obstructive sleep apnea (OSA), the success …
Predictive Value of Infarction Volume on Hemorrhagic Transformation in Ischemic Stroke/TIA With Non-valve Atrial Fibrillation(NVAF) Patients Using Rivaroxaban
This study was aimed at patients with newly diagnosed stroke / TIA associated with nonvalvular atrial fibrillation. We will observe the effect of early using rivaroxaban anticoagulation on hemorrhagic transformation, and explore the predictive value of multi-mode MRI infarct volume / MMP-9 on hemorrhagic transformation after anticoagulation therapy.
Evaluation of Prevalence and Clinical Impact of Atrial Fibrillation in Elderly Patients With Cryptogenic Stroke and High-Risk Patent Foramen Ovale
The purpose of DEFENSE-ELDERLY is to identify the prevalence of AF and evaluate the clinical impact of AF in elderly ESUS patients and no other known sources of stroke besides a high-risk patent foramen ovale, and compare it with elderly ESUS patients without high-risk PFO (no PFO or non-high risk …
Biomarkers of Acute Stroke in Clinic
The proposed study will investigate the clinical use of the ISCDX test that may differentiate between diverse stroke etiologies as listed below: Aim 1: Differentiate between cardioembolic and large artery atherosclerotic ischemic strokes, when hemorrhagic stroke is ruled out, as defined by TOAST classification of subtypes of acute ischemic stroke. …
Outcomes and Safety of Various Conduction System Pacing Methods
The aim of this study is to evaluate safety and clinical outcomes after different pacing approaches of conduction system pacing in a prospective registry.
Long Term Evaluation of Cardiac Arrhythmias After Transcatheter Aortic Valve Implantation -The LOCATE Registry
The purpose of the Long term Evaluation of Cardiac Arrhythmias after Transcatheter Aortic Valve Implantation (LOCATE) Registry is to perform long-term ambulatory monitoring of patients with severe aortic stenosis who undergo trans-catheter aortic valve implantation (TAVI) and develop new onset conduction system abnormalities post-procedure that do not require urgent permanent …
CAB Versus Medical Therapy in Patients With AF and HF With Different EF Categories
This study is to assess the effectiveness and safety of cryoballoon ablation comparing with medical therapy in patients with atrial fibrillation and heart failure with different ejection fraction categories.
Evaluation of 3D Simulation and Planning of Left Atrial Appendage Occlusion Based on 3D Echocardiography
This study aims to compare a semi-automatic 3D echocardiography-based left atrial appendix occlusion procedure planning with FEops, with other imaging modalities for evaluating the left atrial appendage dimensions and device prediction (sizing, deformation) pre-left atrial appendix occlusion , including the current "gold standard", CT- based FEops HEARTguideTM left atrial appendix …
The Basel CardioInsightTM - 3D Mapping Study
This study is to describe the exact location of NOAF-maintaining foci and rotors after cardiac surgery identified by mapping using the non-invasive phase mapping with CardioInsightTM - 3D Mapping technology (CardioInsightTM, Medtronic Switzerland, Tolochenaz, Switzerland) and a low-dose computed tomography scan of the chest.
The DefiPace Study
Prospective, non-interventional, multi-center, international registry in two phases in consecutive patients undergoing elective cardiac surgery. The DefiPace registry is designed in two phases to document the standard of care in 50 patients with atrial fibrillation (AF) to assess the treatment and outcomes of patients with post-operative atrial fibrilllation using low-energy …
