Who could benefit from this research

Could help

Adults with ventricular tachycardia who are candidates for ablation and may benefit from noninvasive radiation-based therapy.

Less likely to help

Patients whose VT is not due to tissue areas addressable by radiation or who cannot tolerate radiation therapy.

What this research studies

Ventricular tachycardia is a dangerous heart rhythm that currently often requires invasive catheter ablation under anesthesia. This grant aims to use targeted radiation to noninvasively destroy the problematic heart tissue and maps infrastructure from imaging, electrophysiology, and radiation oncology to optimize the approach. Researchers will explore how radiation changes heart tissue over time, how quickly effects appear, and how to best identify target sites without surgery. If successful, this could lead to faster procedures with potentially fewer complications for patients with weakened heart function.

Why it matters

Potential benefit: Patients could experience safer, noninvasive treatment options for ventricular tachycardia with potentially shorter procedures and fewer complications.

How similar studies have gone: Early, limited experiences have shown promise for radiation-based ablation but large-scale and long-term data are still needed.
