The value of echocardiography in the staging of preexcitation syndrome and the assessment of left ventricular wall dyskinesia in children.
Review in Frontiers in pediatrics, 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: The incidence of Wolff-Parkinson-White syndrome (WPWs) in the pediatric population is increasing recently. Conventional echocardiography lacks specificity and was limited to assessing the effects of WPWs on cardiac structure, while changes in cardiac function, ventricular wall dysfunction and different subtypes of WPWs were less commonly addressed. Whether WPWs causes cardiac decompensation and ventricular dyskinesia was controversial. Whether echocardiographic multiparameter indices can improve the diagnostic specificity and guide the classification of WPWs and assess the recovery of left ventricular (LV) synchrony and ventricular wall dyskinesia in patients after radiofrequency ablation (RFA) is a very important direction of research. Objectives: To analyse the echocardiographic performance of patients with WPWs: (1) to assess the hazard of WPWs on cardiac function and LV wall dyskinesia using ultrasound multiparameters, with the aim of exploring in depth the pattern of effect of WPWs on cardiac function and motion, (2) to attempt to use echocardiography for staging WPWs, and (3) to predict patient recovery after RFA. Methods: The clinical, echocardiographic and RFA data of 75 children with RFA-confirmed WPWs from January 2019 to December 2024 were retrospectively analysed and compared with 60 healthy controls during the same period. All statistical analyses were carried out using SPSS 26.0 and Results: Two-dimensional echocardiography demonstrated significant LV enlargement, reduced LV systolic function, and significant ventricular wall dyskinesia in 14 of 75 patients, basal segmental septal dyskinesia in 5, and LV posterior wall dyskinesia in 4. The remaining 52 patients did not have significant ventricular wall dyskinesia. Multiparameters showed that WPWs patients compared with healthy controls: GLS (-18.16 ± 3.54% vs. -22.88 ± 0.71%), TD Conclusions: Conventional echocardiography and two-dimensional speckle tracking imaging have the capacity to provide reference data for the reduction of cardiac function and ventricular wall motion disorder caused by WPWs. Furthermore, the longitudinal strain bull's eye map of two-dimensional speckle tracking imaging has the potential to guide the classification of WPWs. Furthermore, a multitude of echocardiographic parameters have been shown to predict the prognosis of recovering post RFA.
