Catheter and echocardiographic-focused management of primary pulmonary vein stenosis in premature infants: a single center 5-year experience.
Article in Journal of perinatology : official journal of the California Perinatal Association, 2026. 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/
objectivesWe describe the outcomes of pulmonary vein stenosis treatment in a cohort of premature infants using an assertive percutaneous management strategy with echocardiography as the primary method of surveillance. SUBJECTS/
methodsThis retrospective study included fifteen premature infants (median 24 weeks gestational age) that underwent pulmonary vein intervention from 2018-2023. The primary outcome was patient survival rate, and the secondary outcome was pulmonary vein preservation rate.
resultsThe estimated patient survival was 100% and 89% at 1 and 2 years after diagnosis. The pulmonary vein preservation rate was 88% and 83% at 1 and 2 years. Patients received a median of 4 echocardiograms between each cardiac catheterization and an average of 1 CT scan for every 1.5 years of observation.
conclusionsPulmonary vein stenosis can be successfully managed with a percutaneous approach to pulmonary vein rehabilitation using echocardiography for surveillance, even in extremely premature infants.
