Proton radiation for dangerous heart rhythms
Part of Heart & circulation clinical trials.
This trial tests a non-invasive radiation treatment aimed at stopping dangerous heart rhythms without surgery. It is for people who have an implantable defibrillator and have not found relief from medications or standard ablation therapy.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 40 years of age or older.
- You have a heart device called an ICD or CRT-D (a small implant that can shock your heart back to a normal rhythm).
- Your heart has had at least 3 dangerous rhythm events (called ventricular tachycardia or fibrillation) in the last 6 months, and medications have not been able to control them.
- You are not a good candidate for the usual treatment (a catheter ablation) because of high risk from your heart condition or other health problems, or you have already tried ablation without success.
- Your heart's pumping function is at least 20% (measured by an ultrasound-like test).
- You have not had prior radiation therapy to the chest area that involved your heart.

This trial studies a non-invasive treatment using focused radiation to target the heart tissue causing dangerous heart rhythms. It may be an option for people who have already had a catheter ablation but still get episodes of ventricular tachycardia.
This study tests a form of focused radiation (SBRT) to treat a dangerous fast heart rhythm called ventricular tachycardia (VT) when medicines and other procedures haven't worked. It may help reduce the number of VT episodes and improve your quality of life.
This trial studies a radiation approach (called stereotactic body radiation therapy, or SBRT) to treat ventricular tachycardia (a dangerous heart rhythm) that keeps coming back. It aims to reduce the rhythm episodes in people who have already tried catheter ablation (a procedure to cauterize rhythm sources) or cannot have it.
This trial studies a new way to treat a dangerous fast heart rhythm (ventricular tachycardia) using targeted radiation to the heart. It is for people who have already tried other treatments and are still having symptoms.
This Phase 2 study tests a precise form of radiation therapy to control recurrent ventricular tachycardia (VT), a dangerous fast heart rhythm. It may help people whose VT keeps coming back despite heart medicines and/or ablation, especially when ablation is not possible.
This trial tests whether a precise, one-time radiation treatment (usually used for cancer) can reduce episodes of a dangerous rapid heartbeat called ventricular tachycardia. It may offer an option for people who have not been helped by other treatments.
