Speckle Strain Analysis of Left Ventricular Dysfunction in Paediatric Patients with Bicuspid Aortic Valve-A Pilot Study.
Article in Children (Basel, Switzerland), 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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/
objectivesBicuspid aortic valve (BAV) is a prevalent congenital heart defect that continues to present a significant challenge in the management of paediatric patients. The assessment of left ventricle systolic function is typically conducted through the measurement of the left ventricular ejection fraction. Currently, left ventricle global longitudinal strain (LV GLS) is regarded as a more sensitive indicator, enabling the quantitative assessment of global and segmental ventricular function through the determination of myocardial deformation.
methodsA prospective study was conducted between 10 January 2023 and 10 January 2024 in a tertiary paediatric cardiology referral centre. The study enrolled children aged 6 to 17 years with BAV who were undergoing periodic evaluation, as well as a control group. The primary objective was to analyse the systolic function (global and segmental LV) using the classical method (LV EF) and speckle tracking echocardiography (STE).
resultsThe study group comprised 73 patients with a mean age of 13 years and was predominantly male. The control group comprised 55 patients. The phenotype IB with aortic regurgitation (AR) was the most prevalent. The results of the STE evaluation in the control group demonstrated mean GLS values between -22.1% and -22.8%. A comparison of the BAV group and the control group revealed a significant difference in GLS for the apical four-chamber view (
conclusionsAlthough the analysis of global LV function demonstrated normal values of EF in patients with BAV, the strain analysis revealed significantly reduced strain in the inferior segment and in the apical four-chamber view, as well as in the anterior segment. Further investigation is required to determine whether reduced LV GLS in paediatric patients with BAV will ultimately result in the development of clinical heart failure. Additionally, it is necessary to ascertain whether this can identify patients with subclinical heart failure and whether early detection can result in a reduction in morbidity.
