When High-Risk Ductal Stenting Goes Wrong: Use of Percutaneous VV ECMO Support and Acute Left Pulmonary Artery Loss.
Article in Pediatric cardiology, 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
Patent ductus arteriosus (PDA) stenting is a vital intervention for neonates with ductal-dependent blood flow, offering an attractive alternative to surgical shunt placement. Despite its benefits, the procedure poses risks such as ductal spasm, branch pulmonary artery compromise, and pseudoaneurysm formation. This report presents two complex neonatal cases with distinct outcomes. The first patient experienced severe ductal spasm, pseudoaneurysm formation, and ductal dissection. Innovative use of percutaneous venovenous extracorporeal membrane oxygenation (VV ECMO) provided hemodynamic stability, enabling staged interventions and eventual successful ductal stenting. The second patient experienced acute left pulmonary artery flow loss due to ductal spasm. Transcatheter attempts to restore flow failed, necessitating surgical stent removal and Blalock-Taussig-Thomas shunt placement. These cases highlight the challenges of PDA stenting in complex ductal anatomies and the importance of advanced imaging, careful wire and catheter selection, and multidisciplinary collaboration. Notably, the first reported use of percutaneous VV ECMO during PDA stenting demonstrates its potential as a lifesaving adjunct for these cases.
