Transcatheter Potts Shunt in Pulmonary Arterial Hypertension After Patent Ductus Arteriosus Closure.
Article in Pulmonary circulation, 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
We report the case of an 18-year-old female with progressive, end-stage pulmonary arterial hypertension (PAH) despite receiving maximal triple combination therapy. The patient had a history of patent ductus arteriosus (PDA) closure at 15 months of age. Due to a pulmonary hypertensive crisis during anesthesia induction, a transcatheter Potts procedure was successfully performed under extracorporeal membrane oxygenation (ECMO) support, involving covered stent implantation just below the previous PDA occluder. At the 3-month follow-up, the patient demonstrated significant clinical improvement, shifting to WHO class II-III, with a dramatic decrease in NT-proBNP (5406-512 pg/ml) and an increased 6-min walk distance (< 300 to 390 m). This case achieved short-term recovery of cardiac function and long-term maintenance of pulmonary vascular stability and demonstrates that the transcatheter Potts shunt is a feasible and effective life-prolonging treatment option for severe PAH, even in patients with a history of prior PDA closure.
