Purpose/Objective:

STereotactic Arrhythmia Radioablation (STAR) showed promising safety and efficacy in patients with refractory ventricular tachycardia (VT) and the STOPSTORM.eu consortium was established to investigate and harmonize STAR treatments in Europe. We investigated current practice on STAR treatment planning through a dedicated benchmark study and now developed best practice consensus guidelines within the STOPSTORM project.

Material/Methods:

Based on the treatment planning benchmark results of the STOPSTORM project, an expert panel drafted treatment planning guidelines for STAR on requirements [1-3], prescription dose [4-5], trade-offs and documentation [6-9], dose inhomogeneity [10-13], dose limitations for cardiac substructures [5, 14-15], beam technique planning [16-17], dose calculation [1,4,18-19], and treatment times [10, 17, 20]. In a two-step process, all participating centers voted and commented on the guidelines in the first step and after further refinements by the expert panel voted on the final guidelines in the second step based on a 5-point Likert scale (1 - strongly disagree to 5 - strongly agree).
