QDOT PAS study
This study is a real-world follow-up of people with symptomatic, drug-refractory paroxysmal atrial fibrillation who were treated with the commercially available QDOT MICRO system together with the VISITAG SURPOINT module. It is a non-randomized, observational sub-study of the REAL AF registry. Eligible patients (either enrolled prospectively or added retrospectively if they meet criteria) will have their treatment and outcomes tracked. Safety is checked from the procedure through the first 7 days after ablation. Effectiveness is measured by whether participants remain free of atrial arrhythmia at 12, 24, and 36 months after the procedure. Participants must be adults who can give consent and can complete follow-up visits. The study does not change clinical care; it records outcomes and any adverse events after standard-of-care treatment with the QDOT MICRO system and VISITAG SURPOINT.
