Conquer-AF Protocol for Redo Ablation Procedures in Recurrent Paroxysmal and Persistent Atrial Fibrillation Using the Sphere-9 Catheter and Affera Ablation System (Conquer-AF)

Conquer-AF is a prospective, multi-center, interventional, non-randomized clinical study that will enroll up to 400 subjects at up to 30 sites across the United States, Europe, and Australia. Subjects diagnosed with symptomatic recurrent paroxysmal or persistent atrial fibrillation after a single prior ablation procedure will be enrolled in this study. Each subject will undergo a study index redo ablation procedure using the Sphere-9 Catheter and Affera Ablation System and will be followed for 12 months. The expected total study duration (from time of first enrollment to the exit of last enrolled subject) is approximately 2 years.

Cryoballoon Pulmonary Vein Isolation for Paroxysmal Atrial Fibrillation

This post-marketing, multi-center, prospective, single-arm, observational study will be conducted across 3 clinical sites in China and enroll no more than 50 patients with paroxysmal atrial fibrillation.

The main questions it aims to answer are: Is the Sphere-9 Catheter and Affera Integrated Mapping and Ablation System safe for treating PAF? Does the treatment help keep patients free from atrial fibrillation and other abnormal heart rhythms during the 12 months after the procedure? Participants will: Have their heart rhythm assessed before and after the ablation procedure. Have PAF treated using the Sphere-9 Catheter and Affera Integrated Mapping and Ablation System. Have follow-up visits at 3, 6, and 12 months after the procedure.

Intracardiac Echocardiography-guided Versus Electroanatomical Mapping-guided Pulsed Field Ablation for Paroxysmal Atrial Fibrillation

This is a prospective, randomized clinical trial, which will be conducted in selected European centers. The objective is to compare two commonly used strategies to guide pulsed-field ablation (PFA) in patients with paroxysmal atrial fibrillation (AF). Patients with paroxysmal AF planned to undergo PFA will be randomized to intracardiac echocardiography (ICE)-guided or electroanatomical mapping-guided (OPAL HDx mapping system) ablation procedure. The primary efficacy endpoint will be freedom from atrial arrhythmia (AF, atrial flutter, atrial tachycardia) recurrence off antiarrhythmic drug therapy and without the need for electrical cardioversion or repeat ablation, with a follow-up duration of 12 months. The primary safety endpoint will be the incidence of predefined safety outcomes.

A Comparative Study of Percutaneous Pulsed Field Ablation Guided by Ultrasound Alone Versus Fluoroscopy in Patients With Atrial Fibrillation

This prospective, randomized, multicenter, open-label, non-inferiority interventional study aims to compare the therapeutic efficacy of percutaneous pulsed field ablation (PFA) guided by ultrasound alone versus fluoroscopy in patients with paroxysmal atrial fibrillation (AF). The success rate of complete electrical isolation of pulmonary veins during the procedure was compared to verify that ultrasound-only guidance is non-inferior to fluoroscopic guidance.

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 mapping and ablation to treat their abnormal heart rhythms and are required to complete 4 follow-up visits at 7 days, 3 months, 6 months and 12 months after the procedure for checkups and tests.

Multi-Centre Based Study Recognition of Atrial Fibrillation With the Corsano CardioWatch 287-2 System

This concerns a multi-center, single-arm, diagnostic accuracy study. In this study, a wristband that monitors heart rythm is assessed in clinical and free living conditions. The performance of the wristband in detecting atrial fibrillation and normal sinus rhythms will be compared to a short 12-lead ECG or 24-hour holter. To ensure that both patients with and without atrial fibrillation are included whilst limiting the burden on patients and hospital staff, four groups of patients are being recruited: * Group A: patients receiving an ECG holter at the outpatient clinic for 24-48 hours of remote monitoring * Group B: patients diagnosed with (paroxysmal) AF presenting to the clinic for routine follow-up evaluation. * Group C: patients diagnosed with (paroxysmal) AF registered in a patient organisation for patients with AF. * Group D: patients receiving a 12-lead ECG at the outpatient clinic as standard of care. The secondary outcomes of the study focus on assessing the primary outcomes in light of demographic subgroups, patient physical activity and the signal quality index.
