FARAPULSE™ Pulsed Field Ablation System
To obtain real world data on the use of, and provide continued evidence on safety and effectiveness of the FARAPULSE™ Pulsed Field Ablation (PFA) system when used per hospitals' standard of care in Chinese population.
Durability of Pulmonary Vein Isolation Using a Variable-Loop Biphasic Pulsed Field Ablation Catheter in Patients With Paroxysmal Atrial Fibrillation
The VARIFY study is designed to find out how durable pulmonary vein isolation (PVI) is after treatment with the VARIPULSE pulsed field ablation (PFA) system in patients with paroxysmal atrial fibrillation (AF). AF is a common heart rhythm disorder caused by abnormal electrical signals coming from the pulmonary veins. In …
Burst Stimulation for Paroxysmal Atrial Fibrillation
Atrial fibrillation (AF) is one of the most common cardiac arrhythmias worldwide, associated with high morbidity and mortality rates. Epidemiological studies in China show that the prevalence of AF in individuals aged ≥60 years ranges from 2% to 3%, with rates continuing to rise due to population aging. Paroxysmal atrial …
Grid eXplore Mapping Study
The purpose of the trial is to find out if the Grid X Mapping Catheter and EnSite X EP System with EnSite X Software v3.1.1, the devices that are being studied, are safe and effective in treating Chinese patients who have atrial fibrillation. Participants will receive a procedure called catheter …
Biomarker-Guided Optimization of Transcutaneous Vagal Stimulation for Atrial (BiG tVNS-AF)
This proposal aims to determine the effects of tVNS on autonomic tone, atrial substrate and neuromodulators in patients with paroxysmal atrial fibrillation (AF), investigate the chronic effects of optimal tVNS on AF burden in patients with paroxysmal AF over a 6-month period, compared with sham stimulation, and identify physiological and …
Clinical Usefulness of Virtual Ablation Guided Catheter Ablation of Atrial Fibrillation: Virtual Rotor Mapping and Catheter Ablation
Radiofrequency catheter ablation is effective in the treatment of patients with paroxysmal atrial fibrillation. In order to reduce the recurrence rate after catheter ablation, the investigators propose to apply 'virtual' ablation on patient-specific atria by simulating 3D atrial computer model. The investigators will conduct virtual rotor mapping in the patient …
Smartwatch and External Holter Monitoring to Detect Atrial Fibrillation in Patients With Cryptogenic Stroke
Stroke recurrence largely depends on the detection of the cause and the control of vascular risk factors, with occult atrial fibrillation (AF) being one of the most important. Prolonged ambulatory cardiac monitoring is recommended for detecting occult AF. Currently, there are non-invasive monitoring devices such as the textile Holter that …
STOP AF First Post-Approval Study
The STOP AF First PAS is a prospective, global, multi-center, observational trial.
EXercise Cardiac Magnetic Resonance Assessment of Left Atrial Mechanics Following Ablation
Longitudinal, observational cohort study to evaluate changes in left atrial (LA) reservoir function during exercise and overall exertional capacity in patients following catheter ablation for paroxysmal atrial fibrillation (AF).
Added Value of Vein of Marshal Ethanol Infusion Compared to Superior Vena Cava Isolation Alone in Patients Undergoing Repeat Ablation for Recurrent Paroxysmal Atrial Fibrillation Despite Durable PV Isolation
The superior vena cava (SVC) is one of the most common non pulmonary vein (PV)-triggers for atrial tachyarrhythmias. SVC electrical isolation can be reached by circular radiofrequency (RF)-ablation under close monitoring of the phrenic nerve. However, adding substrate modification and vein of Marshal (VoM) ethanol infusion to the ablation procedure …
