Computed tomography-based coronary lumen volume to myocardial mass ratio in patients undergoing transcatheter aortic valve replacement: a novel method for risk assessment.
Article in BMC cardiovascular disorders, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundThe coronary lumen volume to myocardial mass (V/M) ratio has been suggested as a quantitative metric of potential imbalance between coronary blood supply and myocardial oxygen demand. This study was designed to assess the prognostic value of the V/M ratio for predicting major adverse cardiovascular events (MACE) in patients undergoing transcatheter aortic valve replacement (TAVR).
methodsThis study enrolled patients who received a standard planning computed tomography (CT) scan before TAVR and dichotomized at the median of 33.31 mm³/g of V/M ratio into groups with low V/M ratio and high V/M ratio. The V/M ratio was calculated by coronary computed tomography angiography (CTA). The endpoint was a composite of all-cause mortality, stroke, and hospitalization for heart failure. The cumulative incidence of the MACE was compared using Kaplan-Meyer plots and uni- and multivariate Cox proportional hazards regression analysis.
resultsIn total, 139 patients were enrolled in this study finally (mean age 71.7 ± 6.7 years, 41.7% female). The mean V/M ratio was considerably lower in patients with MACE than in those without MACE (26.5 ± 4.9mm
conclusionsThe lower V/M ratio could serve as an independent predictor of MACE in patients undergoing TAVR. CLINICAL TRIAL NUMBER: Not applicable.
