Utility of Follow-Up Echocardiograms in Uncomplicated PDA Device Closures Performed During Infancy.

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
introductionGuidelines recommend lifelong follow-up with transthoracic echocardiograms (TTE) for patients who had a patent ductus arteriosus (PDA) device closure via catheterization. The goal of this study was to determine the utility of follow-up TTE in patients who underwent an uncomplicated PDA device closure during infancy.
methodsChart review was performed on patients who had a PDA closure at not more than 1 year of age between January 1, 2002 and June 1, 2020. Patients were excluded if they had other congenital heart disease, did not have a follow-up TTE at least 3 months after procedure, or had a velocity greater than 2.0 m/s in the left pulmonary artery (LPA) or descending aorta (DAo) on the first TTE at least 3 months after device placement. Time points included the first TTE after the procedure, first TTE at least 3 months after procedure, and the most recent TTE.
resultsTotal of 147 infants met the inclusion criteria. Age and weight at initial procedure were 141 ± 217 days and 4.2 ± 2.8 kg. There was no significant difference in DAo velocity between initial and most recent TTE. LPA velocity and left ventricular diastolic Z score significantly decreased between initial and most recent TTE. Seventy-eight patients had repeat echocardiograms more than 1 year after PDA procedure with no change in clinical management. No patient underwent an intervention on the LPA or DAo for stenosis.
conclusionIn patients who underwent an uncomplicated PDA closure during infancy, TTE parameters either stayed stable or improved over time. These findings need to be corroborated in larger studies with longer follow-up. If verified, the long-term TTE guidelines may need to be simplified for this patient population.
