ARRHYTHMIAS, CARDIAC

This study tests a new device called MAGiC that uses magnets to help doctors treat abnormal heart rhythms. About 150 adults who need a standard heart ablation procedure will take part. The goal is to see if the device is safe and works well, both right after the procedure and ove…

This study tests whether a less extensive ablation approach, guided by advanced heart mapping, works as well as standard ablation for people with atrial tachycardia after prior heart surgery or atrial fibrillation treatment. About 100 adults will be randomly assigned to one of tw…

This study tests if a non-invasive radiation treatment (SBRT) can reduce dangerous heart rhythms as well as the standard catheter ablation procedure in 60 people with advanced heart disease. Participants will be randomly assigned to receive either radiation or catheter ablation. …

This study tests a new device (TS-RF system) that uses radiofrequency energy to help doctors safely reach the left side of the heart during procedures for abnormal heart rhythms or mitral stenosis. About 70 adults will be randomly assigned to receive either the new device or a st…

This study tests whether a personalized, sensor-based exercise program can reduce symptoms like palpitations and shortness of breath in people with atrial fibrillation (AF). Researchers will enroll 120 adults with paroxysmal AF who are not very active. Participants will use a dig…

This study is following 8,000 people with heart rhythm disorders (like atrial fibrillation) who are getting a standard catheter ablation procedure using Biosense Webster devices. Researchers are tracking complications and how well the procedure works in everyday medical practice.…

This Stanford study looks at 200 people with persistent atrial fibrillation (AF) who are scheduled for ablation or Maze surgery. Researchers will map the heart's electrical activity to see if the size of organized areas predicts whether the procedure works. The goal is to better …

This study is developing an artificial intelligence system that can track the movement of tumors and nearby organs during radiation therapy without needing implanted markers. Researchers will use data from 300 patients receiving radiation for various cancers or heart arrhythmias …

This study collects blood and tissue samples from 2,000 adults with or without heart rhythm problems. Researchers will look for genetic differences that may cause arrhythmias. No treatment or medication is given—the goal is simply to learn more about the genes involved.

This study at Stanford University is testing whether a computer program can help doctors predict which patients with atrial fibrillation (an irregular heartbeat) will benefit from a procedure called ablation. About 120 adults who are already scheduled for ablation will have their…

This study is testing a digital app called VIRTUES that helps people with heart conditions manage their health from home. The app provides personalized recommendations on topics like blood pressure, cholesterol, and lifestyle changes. Researchers will enroll 2000 participants to …

This study looks at 500 people who have had a stroke and also have atrial fibrillation (an irregular heartbeat). The goal is to understand why some people still have strokes even when taking blood thinners. Researchers will collect blood samples and heart ultrasound images to fin…
