Percutaneous device closure of iatrogenic right ventricular perforation during attempted ventricular septal defect closure: a case report.
Article in Oxford medical case reports, 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
Cardiac perforation is a rare but life-threatening complication of transcatheter cardiac procedures, particularly in children where tissue fragility increases risk. We present a rare case of iatrogenic right ventricular perforation during transcatheter ventricular septal defect closure in a pediatric patient. During the procedure, inadvertent withdrawal of the Terumo guidewire caused perforation of the right ventricular apex, leading to cardiac tamponade and cardiopulmonary arrest. Emergency pericardiocentesis with pigtail catheter placement and autotransfusion restored hemodynamic stability, after which transcatheter repair was selected over surgical intervention due to the patient's critical condition. An 8 mm Shanghai Shape Memory Alloy occluder was successfully deployed to seal the perforation, resulting in complete hemostasis and a stable recovery. This case highlights that transcatheter device closure can serve as a life-saving alternative to emergent surgery for iatrogenic cardiac perforations in children, offering a minimally invasive solution in high-risk scenarios.
