Zapping heart scars: could one radiation dose replace drugs for dangerous rhythms?

This study tests a non-invasive radiation treatment called STAR for people with a dangerous fast heart rhythm caused by heart scarring. Instead of using medications or a catheter procedure, a single targeted dose of radiation is delivered to the scarred area. The goal is to see if this approach is safe and effective as a first treatment, reducing the need for ICD shocks and improving quality of life. The trial will enroll 20 adults and follow them for one year.
