Evaluating the QDOT MICRO System for Atrial Fibrillation

This study is looking at the long-term safety and effectiveness of a medical device called the QDOT MICRO System, used with the VISITAG SURPOINT Module, to treat symptomatic paroxysmal atrial fibrillation (a type of irregular heartbeat that starts and stops on its own). Researchers want to see how well this system works and if it's safe for people who haven't responded to other treatments. You might be able to join if you are 18 or older, have this type of atrial fibrillation, and your doctor thinks you could benefit from an ablation procedure (a treatment that uses heat or cold to create tiny scars in the heart to block faulty electrical signals). The study aims to enroll 250 participants, but its current status is unclear.

Study design
This is an observational study, meaning researchers will watch how the QDOT MICRO System is used in real-world settings. It is a sub-study within a larger registry, and it is not randomized.
What's involved
You would need to complete scheduled assessments within 12 months after your ablation procedure, and then two more assessments at 24 and 36 months.
Compensation
Not stated in the trial record.
Follow-up
Participants will be followed for safety for 7 days after the procedure, and for effectiveness at 12 months, 24 months, and 36 months.
