Myocardial deformation in children post cardiac surgery, a cross-sectional prospective study.

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
backgroundMyocardial deformation by speckle tracking echocardiography provides valuable information on the left ventricular function. The study aims to assess myocardial deformation in terms of left ventricular strain as an indicator of myocardial function in children after cardiac surgery at outpatient follow-up visits.
methodsThe study design was a prospective observational cross-sectional study that included pediatric patients after biventricular cardiac surgery during the postoperative follow-up visits in the outpatient department. In addition to conventional echocardiographic examination, two-dimensional speckle tracking echocardiography was done to evaluate myocardial deformation in terms of left ventricular strain. Echocardiographic measurements were done offline and were compared to published reference normal values for age. Study subjects were divided according to age at follow-up into four groups (1 month-1 year, 1-2 years, 2-5 years, and 5-11 years).
resultsOver ten months, 100 patients (64 males and 36 females) were included in the study. The median age was 30.8 months (IQR 12.8-65.3 months), the median weight was 11.7 kg (IQR 8-17 kg) and the median duration after surgery was 7.3 months (IQR 3.2-30.8 months). Longitudinal strain values were significantly (p < 0.001) lower than reference values for different age groups. Global circumferential strain showed no significant difference from the reference values. The duration after surgery had a statistically significant effect on longitudinal strain values, with improvement of the strain values with increasing intervals after surgery.
conclusionUsing myocardial deformation method to evaluate cardiac function may detect underlying cardiac function abnormalities even with normal traditional functional parameters, which could have implications for patient management and follow-up.
