ATRIAL FLUTTER

This study will compare two widely used blood thinners, apixaban (Eliquis) and rivaroxaban (Xarelto), in about 10,000 veterans with atrial fibrillation (an irregular heartbeat). The goal is to see which drug better prevents strokes and major bleeding. Participants must already be…

This study looks at whether it's safe to wait 5-9 days before treating a sudden episode of atrial fibrillation or flutter, instead of treating it right away in the emergency room. About 500 patients who are stable enough to go home will be randomly assigned to either immediate tr…

This study tests a monthly injection called abelacimab to prevent strokes in about 1,900 people with atrial fibrillation (an irregular heartbeat) who cannot safely take standard oral blood thinners. Participants will receive either the drug or a placebo, and researchers will trac…

This study looks at whether starting treatment early for atrial fibrillation (AF) that is only detected by heart devices can help control the condition. About 520 adults with these hidden AF episodes will be randomly assigned to either early rhythm control therapy (medication, sh…

This study tests whether heart failure patients who fully recover after treatment for a fast heart rhythm (like atrial fibrillation) can safely stop their heart failure medications. 348 participants will be randomly assigned to either gradually stop their drugs or continue them a…

This study tests a new circular-shaped catheter that uses pulsed field energy to treat atrial fibrillation and atrial flutter. About 150 adults will receive the procedure, guided by ultrasound inside the heart. The goal is to see if the catheter safely and effectively blocks abno…

This study tests whether closing a small pouch in the heart (the left atrial appendage) with a device is safer and as effective as long-term blood thinners for people with atrial fibrillation who have already had a brain bleed. About 530 participants will be randomly assigned to …

This study tests whether a special CT scan done in the emergency department can quickly check for blood clots in people with atrial fibrillation or atrial flutter. If no clot is found, doctors can proceed with a procedure to restore normal heart rhythm (cardioversion) right away.…

This study is testing a mobile app called Cardio2U for people with atrial fibrillation or heart failure. The app helps patients track their condition, learn about their disease, and communicate with their care team. Researchers will check if patients find the app easy to use and …

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 compares two catheters used during a common heart procedure for atrial fibrillation. The goal is to see if one catheter can confirm that the treatment worked faster than the current method. Thirty adults with persistent atrial fibrillation or atrial flutter will be enr…

This registry collects information from 1,000 patients who have had or will have a heart rhythm procedure at University Hospital Düsseldorf. The goal is to track safety and success of these standard procedures in everyday care. No new treatments are being tested; instead, researc…
