Clinical Impact of Flow-Adjusted Transprosthetic Pressure Gradient After Aortic Valve Replacement.
Article in Annals of thoracic surgery short reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background: It is still controversial whether prosthesis-patient mismatch (PPM) adversely affects long-term outcomes after aortic valve replacement (AVR). The aim of this study was to examine whether flow-adjusted pressure gradient is a valid new indicator of long-term outcomes. Methods: Data collected from 184 patients undergoing isolated AVR for severe aortic stenosis from October 2012 to September 2016 were analyzed. Flow-adjusted pressure gradient was defined as mean pressure gradient divided by stroke volume (MPG/SV). The effect of PPM and MPG/SV on long-term cardiac events and survival was evaluated. Results: Overall mortality was 8.2%, and the incidence of cardiac events was 9.2% (median follow-up period, 5.5 years). Moderate to severe PPM was present in 30.0% of patients and did not correlate with cardiac events ( Conclusions: Flow-adjusted pressure gradient has the potential to be a better predictor of long-term outcomes after AVR.
