Pulmonary Impedance and Wave Reflections in Adults with Mitral Stenosis: Immediate and Follow-Up Effects of Balloon Valvuloplasty.
Article in Annals of biomedical engineering, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
purposeWe compared adults with mitral stenosis (MS) to 8 controls (CONT) to see how pulmonary impedance and wave reflections differ at baseline and after balloon valvuloplasty.
methodsWe separated the MS patients into groups according to mean pulmonary artery pressure: moderate (MOD; ≤ 26 mmHg, n = 21) and high (HIGH; > 26 mmHg, n = 33). We made baseline high-fidelity measurements in all patients, in the MS groups after vasodilation with nitroprusside, immediately and 4 months after balloon valvuloplasty.
resultsComparing MOD vs CONT, using the Kruskal-Wallis test with Bonferroni correction, reveals evidence for higher baseline input resistance (R) (489 vs 205 dyne-sec/cm
conclusionMS causes alterations in pulmonary hemodynamics that differ according to pressure levels. These changes are only partially reversed immediately after valvuloplasty. There is evidence for reverse remodeling 4 months afterwards.
