Evaluation of the intraventricular hemodynamics of patients with left ventricular dysfunction via vector flow mapping.
Article in Frontiers in cardiovascular medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Background: Vorticity, measured via new vector flow mapping (VFM), a quantitative marker of vortex dynamics, can reflect hemodynamic changes more sensitively, potentially offering complementary information to conventional echocardiographic indices of cardiac function. Aims: We investigated left ventricular hemodynamics in both normal subjects and patients with left ventricular dysfunction to explore the probability of evaluating cardiac function with the assistant index, the highest vorticity value of a vortex (Vort-max). Methods: Sixty subjects were divided into 3 groups, namely, the control group, Group I (HFpEF) and Group II (HFmrEF&HFrEF), and examined via conventional echocardiography. VFM was performed from the apical 5-chamber view to calculate the vorticity during diastole and systole in the left ventricle. Results: Hemodynamic changes were obvious during diastolic dysfunction. The Vort-max-base values of early and late diastole in Group I were greater than those in the control groups ( Conclusions: Blood flow energy was detected in patients with diastolic and systolic dysfunction by using Vort-max derived from vector flow mapping. The vorticity value could be a novel parameter for evaluating the hemodynamic changes in the left ventricular cavity and cardiac diastolic function.
