Outcomes Following Balloon Pulmonary Valvuloplasty in Symptomatic Neonates With Tetralogy of Fallot-A CCRC Study.
Article in Journal of the Society for Cardiovascular Angiography & Interventions. 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: Complete repair (CR) can be delayed in neonates with symptomatic tetralogy of Fallot (sTOF) using surgical or transcatheter palliation to relieve cyanosis. Balloon pulmonary valvuloplasty (BPV) is an established treatment for pulmonary valve stenosis; however, its effectiveness in palliating neonates with sTOF has not been well investigated. Methods: A retrospective chart review between 2005 and 2017 on neonates with sTOF who underwent initial BPV from 9 participating centers of the Congenital Cardiac Research Collaborative was performed. Primary outcome was CR at >30 days after BPV without interval reintervention (RI). Results: In total, 47 neonates with sTOF underwent BPV, of whom 27 (57%) underwent CR at >30 days after BPV without RI. The median time to CR was 151 days (106-210). RI before CR occurred in 17 patients (36%): surgical shunt (n = 7), outflow tract stenting (n = 6), patent ductus arteriosus stenting (n = 2), and surgical outflow patch (n = 2). Valve-sparing repair at CR was performed in 6 patients (13%) after initial BPV. RI or CR ≤30 days from BPV was associated with smaller infundibular diastolic diameter ( Conclusions: BPV can be an effective palliative therapy in select neonates with sTOF to delay CR. A smaller diastolic infundibulum diameter is a predictor of RI or early CR, and valve-sparing repair is uncommon, making patient selection and alternative palliative methods key when considering BPV palliation in neonates with sTOF.
