Pre-procedural three-dimensional computed tomography vs. angiographic assessment for patent ductus arteriosus stenting: a comparative analysis.
Article in Frontiers in cardiovascular medicine, 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
Background: Patent Ductus Arteriosus (PDA) stenting has become an established albeit complex intervention in ductal dependent congenital heart disease. Accurate pre-procedural planning is essential for successful stent placement, yet the optimal measurement methodology remains debated. This study compared the accuracy and clinical utility of routine pre-procedural three-dimensional (3D) computed tomography-derived measurements with traditional angiographic assessments for PDA stent sizing. Methods: We analyzed 21 consecutive PDA stenting cases from Sheba Medical Center (01/2021-10/2023) with a median age of 14 days (IQR: 8-19) and mean weight of 3.6 ± 2.2 kg. Patients were stratified by anatomical complexity: Group 1 (0 turns, Results: In the overall cohort, both 3D ( Conclusion: Pre-procedural 3D measurements provide consistent reliability across varying degrees of anatomical complexity, offering an advantage in cases with moderate tortuosity where angiography may be vulnerable to foreshortening. Angiography remains highly accurate for straightforward anatomy. A complexity-stratified imaging approach is recommended to optimize stent selection.
