Outcomes of surgical versus transcatheter aortic valve replacement in patients with low-flow, low-gradient aortic stenosis.
Observational study in The Journal of thoracic and cardiovascular surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled it.
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
objectiveThis study sought to determine the impact of surgical versus transcatheter aortic valve replacement in patients with low-flow, low-gradient aortic stenosis.
methodsThis was an observational study of consecutive aortic valve replacements for severe aortic stenosis from 2010 to 2023. Patients with low-flow, low-gradient aortic stenosis (aortic valve mean gradient <40 mm Hg and a stroke volume index <35 mL/m
resultsA total of 575 patients underwent isolated, first-time aortic valve replacement for low-flow, low-gradient aortic stenosis, of whom 248 (43%) were low operative risk (Society of Thoracic Surgeons Predicted Risk of Mortality <4%). A total of 131 patients (52.8%) underwent surgical aortic valve replacement, and 117 patients (47.2%) underwent transcatheter aortic valve replacement. Those undergoing transcatheter aortic valve replacement were older than those undergoing surgical aortic valve replacement: 79.0 [76.0-84.0] years versus 66.0 [59.0-73.0] years (P < .001). The incidence of 30-day mortality, stroke, and pacemaker was not different across each group, but the incidence of paravalvular leak was higher in the transcatheter aortic valve replacement group. At 1-year follow-up, aortic valve mean gradient (9.0 [7.0-12.0] mm Hg) and ejection fraction (55.0% [40.0-60.0]) were no different across each group. On multivariable analysis, transcatheter aortic valve replacement was not associated with an increased hazard of death compared with surgical aortic valve replacement (hazard ratio, 1.38, 95% CI, 0.72-2.66, P = .34) or an increased hazard of heart failure readmission (hazard ratio, 1.70, 95% CI, 0.88-3.30, P = .11) compared with surgical aortic valve replacement.
conclusionsFor patients with low-flow, low-gradient aortic stenosis, surgical and transcatheter approaches to aortic valve replacement may be equally as advantageous with respect to long-term outcomes.
