Transcatheter Closure of a Congenital Gerbode Defect in a Child.
Article in JACC. 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
backgroundThe Gerbode defect is a rare left ventricular-to-right atrial communication (<1% of congenital heart defects). Percutaneous closure is a well-established alternative to surgery, although pediatric evidence remains limited. CASE SUMMARY: A 12-year-old girl with a neonatal-onset holosystolic murmur was lost to follow-up at age 3 after a canceled surgical repair; she returned to care 9 years later after remaining asymptomatic. Transesophageal echocardiography confirmed a 4-mm type II congenital Gerbode defect-a perimembranous ventricular septal defect with anomalous tricuspid chordal insertion causing indirect left-to-right shunting. She successfully underwent transcatheter closure using a 4-mm muscular ventricular septal defect occluder. DISCUSSION: This case demonstrates safety and feasibility of off-label occluder use in pediatric type II Gerbode defects, particularly when cultural beliefs preclude open-heart surgery. TAKE-HOME MESSAGES: Transcatheter closure is safe and effective in selected pediatric Gerbode defects. Detailed echocardiographic assessment is essential for characterization, procedural guidance, and misdiagnosis avoidance.
