Medtronic Cardiac Ablation Solutions

This study is testing a new device called the Sphere-9 catheter, used with the Affera mapping system, to treat ventricular tachycardia (VT) — a fast, dangerous heart rhythm. The procedure uses heat to destroy small areas of scarred heart tissue that cause the abnormal rhythm. The…

This study tests a new catheter system called SpherePVI that uses heat to destroy tiny areas of heart tissue causing atrial fibrillation (an irregular heartbeat). About 150 people with symptomatic atrial fibrillation will undergo the procedure. The goal is to see if the device ca…

This study tests a new device that uses heat to destroy tiny areas in the heart causing short bursts of irregular heartbeat (paroxysmal atrial fibrillation). About 300 adults with this condition will receive the procedure and be monitored for a year. The goal is to see if the tre…

This study follows 200 people with a common type of irregular heartbeat (paroxysmal atrial fibrillation) who are treated with a special freezing catheter. The device, called Arctic Front, freezes small areas of heart tissue to block faulty electrical signals. Researchers will tra…

This study is for people who still have atrial fibrillation (an irregular heartbeat) after a first ablation procedure. It will test a new catheter system (Sphere-9 and Affera) to see if a second ablation can safely and effectively restore a normal heart rhythm. About 400 particip…

This study follows 580 adults with atrial fibrillation who are treated with the PulseSelect PFA system, a device that uses electrical pulses to fix irregular heartbeats. Researchers will monitor participants for 36 months to see how well the procedure prevents heart rhythm proble…

This study follows up to 1,950 people with atrial fibrillation who are treated with the PulseSelect PFA system, a device that uses electrical pulses to correct irregular heartbeats. Researchers will track how well the procedure prevents abnormal heart rhythms and whether any seri…

This study tests a new device, the SpherePVI catheter, to treat a heart rhythm problem called atrial fibrillation (AFib). About 100 adults with AFib will receive this treatment to see if it safely and effectively restores normal heart rhythm by isolating the veins that trigger th…

This registry will follow 540 people with atrial fibrillation who are treated with the Affera ablation device. Researchers want to see how well the device stops irregular heart rhythms and how safe it is in everyday medical practice. The study is observational, meaning patients g…
