Major objective is to compare the efficacy of adding additional ablation step (targeting areas of complex, continuous electrical activity in LA) beyond Re-PVI during catheter ablation of Atrial Fibrillation (AF) in patients undergoing 2nd ablation procedure. Underlying hypothesis that in addition, to Re-PVI, an ablation step targeting areas of complex continuous activity will increase atrial arrhythmias freedom compared to Re-PVI only ablation.
In this prospective cohort study, the investigators aim to investigate the incidence of ICM-detected AF in unselected ischemic stroke patients and its association with anticoagulation initiation and stroke recurrence.
The real world study is a retrospective and/or prospective, single-center, single-arm observational study to observe the safety and effectiveness of the FARAPULSE Pulsed Field Ablation System for treatment of recurrent, symptomatic Paroxysmal Atrial Fibrillation (PAF) in a Chinese population.
The recurrence of atrial fibrillation(AF) after pulmonary vein ablation with cryoballoon is conducted by many factors . The previous studies found larger left atrial and longer AF duration are tied to higher risk of AF recurrence. The characters of ablation procedure is also of critical importance to durable clinical success such as temperature features and time-to-isolation (TTI). The aim of our study is to develop an tool of recurrence risk evaluation with both pre-procedure and procedure factors.
This is a post-market, prospective, observational study to evaluate the accuracy of KODEX 3D-imaging. The research study will collect pre-operative and post-operative cardiac imaging data from adult arrhythmia patients who are already undergoing catheter-based electrophysiological (EP) intervention (ablation procedures) using the FDA approved medical device KODEX - EPD™ system.
Recurrence of atrial fibrillation (AF) after a pulmonary vein isolation (PVI) procedure is frequent. Current follow up with Holter monitoring and electrocardiograms (ECG) during outpatient clinic consultations cover only short time stretches and require hospital visits. Mobile health solutions with rhythm monitoring using photoplethysmography (PPG) technology on a smartphone could extend rhythm monitoring time, while lowering hospital visits and cost. This study aims to compare the performance of a digital health solution using PPG technology on a smartphone versus the current standard of care to monitor for AF recurrence after a PVI procedure.
The ARIES study is an observational study in which patients with a recent acute ischemic stroke of cryptogenic aetiology are consecutively enrolled in order to perform a extensive cardiologic work-up. The main objective is to study parameters that could predict arrythmias on prolonged monitoring and also echocardiographic parameters of left atrial disfunction that could predict the presence of a hidden atrial fibrilation and recurrent ischemic events in patients with cryptogenic stroke.
This post-market global registry will evaluate the ability of the Ablamap® Software to identify atrial fibrillation sources and guide ablation therapy in patients with atrial fibrillation.
Collect electrophysiological data during atrial fibrillation (AF) ablation procedures to assess the performance of a Signal Complexity Visualization algorithm designed to be integrated into the CathVision ECGenius® System.
Multi-center, international, non-randomized clinical trial evaluating the use of Volta's VX1 algorithm as used in combination with repeat catheter ablation after AF recurrence after previous catheter ablation.
