Two-dimensional speckle tracking echocardiography in fetuses with critical aortic stenosis before and after fetal aortic valvuloplasty.
Article in Archives of gynecology and obstetrics, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundCritical aortic stenosis (AS) in fetuses may progress to hypoplastic left heart syndrome (HLHS) with need for postnatal single ventricular (SV) palliation. Fetal aortic valvuloplasty (FAV) is performed to achieve postnatal biventricular (BV) circulation. However, the impact of FAV on fetal myocardial function is difficult to measure. Prediction of postnatal circulatory status and, therefore, counseling is challenging.
methodsRetrospective study of fetuses with critical AS who underwent FAV. Global Longitudinal Peak Systolic Strain (GLPSS) of the left ventricle (LV) and right ventricle (RV) were retrospectively analyzed before and after intervention. Fisher's Exact Test and Mann-Whitney-U Test were used for univariant statistical analysis.
results23 fetuses with critical AS were included. After intervention fetuses demonstrated more negative LV-GLPSS mean values post- vs. pre-intervention (- 5.36% vs. - 1.57%; p < 0.05). RV-GLPSS was decreased in all fetuses, there was no peri-interventional change. 20 fetuses were born alive. Postnatally, 10 had BV and 10 SV circulation. Improved post-interventional LV-GLPSS strain values correlated with BV outcome (p < 0.05). Pre-interventional continuous LV-GLPSS values correlated with postnatal SV vs. BV outcome (p < 0.05).
conclusionIn some fetuses, LV myocardial function assessed by speckle tracking echocardiography (STE) improves after FAV. Improved post-interventional LV-GLPSS correlates with biventricular postnatal outcome. Furthermore, pre-interventional LV- and RV-GLPSS correlate with postnatal outcome. Further studies are needed to asses, if pre-interventional STE parameters might predict which fetuses will benefit from FAV with postnatal BV circulation.
