Assessment of atria function after percutaneous closure of atrial septal defect using 2D speckle tracking echocardiography.

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
backgroundPercutaneous occlusion of atrial septal defect (ASD) has recently become a standard therapeutic strategy, but little is known about atria function thereafter. Strain analysis by two-dimensional speckle tracking echocardiography (2D-STE) is considered to be a new tool to assess myocardial function.
methodsThis study aimed to evaluate atria function by quantifying longitudinal strain in patients with chronic RV volume overload due to ASD before and after percutaneous closure using 2D-STE. 28 consecutive patients underwent percutaneous closure of ASD (18 female, 10 male) were examined, clinical and echocardiographic evaluation one day before, 1 day, and one month after percutaneous closure of ASD. Peak longitudinal systolic strain and strain rate of both atria were analyzed by 2D-STE.
resultsMean age of the patients was 15.07 ± 8.39 years; mean diameter of ASD was 16.01 ± 2.78 mm; left atrium (LA) diameter significantly increased after ASD closure; and peak longitudinal strain of RA increased significantly one day and one month after ASD closure (48. 77 ± 4.40, vs.55.36 ± 3.70 and, vs. 62.13 ± 3.81%, p = 0.001). LA longitudinal strain significantly decreased after ASD closure (42.55 ± 4.57, vs. 34.79 ± 3.20%, p = 0.001). Furthermore, negative correlation was found between the size of the ASD and delta LA systolic strain and strain rate.
conclusions2D-STE can be considered a feasible and simple technique for assessment of atrial deformation in ASD patients, and it useful to assess the effect of percutaneous ASD closure on atrial reservoir function by measuring peak atrial longitudinal strain.
