ATRIAL ARRHYTHMIA

This study tests a new two-step procedure for people with long-standing persistent atrial fibrillation (AFib), a type of irregular heartbeat. The procedure combines a minimally invasive surgery on the outside of the heart with a standard catheter ablation inside the heart. Resear…

This study will test an AI software called Volta AF-Xplorer II during catheter ablation for atrial fibrillation. About 150 adults will be treated in real-world clinics, and researchers will track how well the AI helps guide the procedure. The goal is to see if the AI improves saf…

This study is tracking 300 people with paroxysmal or persistent atrial fibrillation (AFib) who are treated with the Volt PFA System, a balloon-based device that uses pulsed field ablation to correct irregular heart rhythms. Researchers are monitoring safety—looking for serious si…

This study compares two types of pacemaker placement after a procedure called AV node ablation for people with atrial fibrillation and normal heart function. One method uses standard right ventricular pacing, while the other targets the left bundle branch area. The goal is to see…

This study tests whether a newer, two-step hybrid ablation procedure works better than standard catheter ablation for people with persistent atrial fibrillation (a type of irregular heartbeat) and heart failure. About 120 participants will be randomly assigned to one of the two p…

This study looks at whether scarring (fibrosis) in the heart's upper chambers can predict who will develop an irregular heartbeat after heart surgery. Researchers will track 50 adults aged 40+ with no prior irregular heartbeat who are scheduled for heart surgery. The goal is to s…

This study tests a new imaging system called VERAFEYE that helps doctors see inside the heart during a common procedure called catheter ablation. The procedure treats irregular heartbeats like atrial fibrillation. About 50 adults will take part to see if the system works well and…

This study is testing a new 3D imaging system that helps doctors see inside the heart during a procedure to treat atrial flutter and atrial fibrillation. About 50 adults who are already scheduled for a catheter ablation will have their procedure guided by this system. The goal is…

This study examines whether special pacemakers can effectively treat a common type of fast heart rhythm (atrial tachycardia) in people born with heart defects. Researchers will review medical records from up to 300 patients over 10 years to see if the pacemaker reduces the need f…
