Cardiac RadiothErapy For hEart faiLure
Sponsor: Universitaire Ziekenhuizen KU Leuven
Summary
Preliminary data suggests that patients suffering from advanced refractory heart failure (HF) could benefit from single low dose whole heart external beam radiotherapy (EBRT). Objective: To explore in our center the efficacy of administering a EBRT treatment of 5Gy to the whole heart in patients with advanced and refractory HF. The hypothesis is that 5Gy EBRT to the whole heart can improve the left ventricular ejection fraction (LVEF) of these patients by a clinically relevant 5%. Main study endpoints: The primary aim is to explore the efficacy of EBRT treatment for advanced refractory HF. Secondary endpoints include an assessment of safety, overall survival, hospital admissions, late toxicity, quality of life and the effect of the treatment on other heart function indicators (left ventricular volumes, NT-proBNP, Troponine, High sensitive CRP).

Interventions
5 Gray Whole Heart external beam radiotherapy
EBRT will be delivered with photon energies restricted to 6 Megavoltage (MV) using intensity modulated radiotherapy (IMRT) or Volumetric modulated arc therapy (VMAT). Patients will be treated with a single fraction treatment up to a dose of 5Gy prescribed to the 95% PTV-encompassing isodose line (PTVD95% ≥5Gy). The near-maximum dose is limited to 5.35Gy (PTV D2% ≤ 5.35Gy). The treatment can be performed both as an inpatient or outpatient procedure.
