Optimizing cardio-respiratory motion management in stereotactic arrhythmia radioablation through mid-position planning target volume.
Article in Journal of applied clinical medical physics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
PURPOSE/
objectiveThis study proposes an implementation of the mid-position (MidP) approach to compensate for cardio-respiratory motions in the context of Stereotactic Arrhythmia Radioablation (STAR) and evaluates its benefits compared to an internal target volume (ITV) approach. MATERIALS AND
methodsFifteen patients who underwent STAR for refractory ventricular tachycardia in our institution were included in this retrospective planning study. For each patient, a cardiac-gated four-dimensional computed tomography (4D-CT
resultsCompared with the ITV method, the MidP approach resulted in a mean [min-max] relative PTV volume reduction of 30% [19%, 48%] (p < 0.001, Wilcoxon signed rank test). The mean [min-max] D95% CTV coverage was 105% [101%-114%] and 107% [101%-117%] of the prescription dose for MidP and ITV-based plans, respectively. The median dose to the whole heart was significantly lower with MidP-based plans with a mean difference of -0.5 Gy (p = 0.0084). The near-maximum dose (D1%) delivered to left coronary arteries, aorta, and stomach was systematically lower with the MidP-based plans.
conclusionCompared to ITV based approach, the use of MidP strategy for treatment planning of STAR leads to significantly smaller PTV and lower surrounding OAR doses while still achieving a clinically acceptable CTV coverage.
