Concentric Stenting of the Right Ventricular Outflow Tract in Complex Multilevel Obstruction.
Article in JACC. Case reports, 2025. 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
backgroundTetralogy of Fallot (TOF) with pulmonary atresia and major aortopulmonary collateral arteries (MAPCAs) presents significant challenges in management in the presence of right ventricular (RV) hypertension secondary to multilevel right ventricular outflow tract (RVOT) obstruction. CASE SUMMARY: A 5-month-old boy with a history of TOF, pulmonary atresia, and MAPCAs who underwent MAPCA unifocalization and TOF repair presented with suprasystemic RV pressures. Diagnostic catheterization showed severe RVOT obstruction at the conduit insertion site owing to the presence of concentric muscle bundles, which was treated with overlapping bare metal stents given his high-risk surgical candidacy. DISCUSSION: Stent fracture is a recognized complication; however, this case demonstrates that concentric stenting can effectively relieve RVOT obstruction in patients who are not surgical candidates. TAKE-HOME MESSAGE: Concentric stenting of the RVOT is a viable option for managing complex RVOT obstruction in pediatric patients with congenital heart disease who are not surgical candidates.
