Bringing the Cath Lab to the Neonatal Intensive Care Unit (NICU): A Three-Case Series About Bedside Echocardiography-Guided Transcatheter Patent Ductus Arteriosus Closure in Extreme Low Birth Weight Infants.
Article in Cureus, 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) remains a significant driver of morbidity in extreme low birth weight (ELBW) infants. Pharmacological closure often fails or is contraindicated, while surgical ligation carries significant perioperative and postoperative risks. Recent advances in device technology have enabled transcatheter PDA closure in very small infants, including procedures performed at the bedside in the neonatal intensive care unit (NICU). We report a case series of three ELBW infants (gestational age 24-27 weeks; weight at procedure 1.0-1.28 kg) who successfully underwent bedside transcatheter PDA closure using the Amplatzer Piccolo Occluder (Abbott Structural Heart, Plymouth, MN) under echocardiographic guidance in the NICU. These infants remained ventilator dependent due to hemodynamically significant PDA (hsPDA) and had failed medical therapy. Technical success was achieved in all cases without immediate device-related complications; two infants demonstrated significant respiratory improvement with successful extubation following the procedure. One infant, despite successful PDA device occlusion, passed away due to complications related to extreme prematurity, necrotizing enterocolitis, and nosocomial sepsis. This case series highlights the feasibility, safety, and potential respiratory benefits of bedside transcatheter PDA device occlusion in ELBW infants when performed by an experienced multidisciplinary team.
