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.

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.

Real-world Safety and Effectiveness Registry of Catheter Ablation of Paroxysmal Atrial Fibrillation as Initial Control Therapy With the Thermocool SmartTouch SF Catheter (A Sub-study of REAL AF Registry)

To generate real-world evidence from the parent study, REAL AF registry, on the use of Thermocool SmartTouch SF (STSF) catheter in ablation for the treatment of paroxysmal atrial fibrillation (PAF).

Pulsed Field Ablation of SVC and PV in Paroxysmal Atrial Fibrillation (PASPA Study)

The PASPA study is a multicenter, randomized trial comparing Pulmonary Vein Isolation (PVI) alone versus PVI plus Superior Vena Cava Isolation (SVCI) using Pulsed Field Ablation (PFA) in patients with paroxysmal atrial fibrillation (PAF). 650 participants will be followed for 12 months. The main goal is to see if adding SVCI reduces arrhythmia recurrence without increasing complications such as phrenic nerve injury or sinus node dysfunction.

Clinical Study on the Efficiency of Rapid Arrhythmia Mapping Using EasyStars™ High Density Mapping Catheter Applications

The primary objective of this study was to evaluate the clinical feasibility, safety, and surgical characteristics of the EasyStars™ High Density Mapping Catheterin in patients with complex arrhythmias.

A Clinical Study on the Use of a Domestically Produced Cryoablation System Combined With Balloon Cryoablation Technology for the Treatment of Paroxysmal Atrial Fibrillation

To validate the safety and efficacy of balloon cryoablation technology and the accompanying disposable intracardiac mapping electrode catheter and adjustable guide sheath for the treatment of paroxysmal atrial fibrillation.

A Clinical Study on the Use of a Domestically Produced Three-dimensional Cardiac Electrophysiological Mapping System Combined With Pressure Monitoring Technology and Star Mapping Technology for the Treatment of Paroxysmal Atrial Fibrillation.

Validating the safety and efficacy of pressure monitoring technology and star-shaped marking technology for the treatment of paroxysmal atrial fibrillation

A Prospective Clinical Study to Evaluate the Safety and Effectiveness of Pulmonary Vein Isolation Plus Box Isolation of Fibrotic Areas With the Globe® Pulsed Field System for Treating Patients With Symptomatic Paroxysmal or Persistent Atrial Fibrillation

The study will evaluate the safety and 12-month effectiveness of the Pulmonary Vein Isolation plus Box Isolation of Fibrotic Areas (BIFA) ablation strategy with the Globe Pulsed Field System (Globe PF System) for the treatment of atrial fibrillation.

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.
