Anomalous Right Coronary Artery Intervention Guided by Patient-Specific 3-Dimensional Printed Modeling.
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
backgroundPercutaneous coronary intervention (PCI) of an anomalous aortic origin of a coronary artery (AAOCA) is technically challenging given difficult engagement and poor support. While coronary computed tomography angiography aids planning, it lacks the tactile simulation provided by patient-specific 3-dimensional (3D) modeling. CASE SUMMARY: A 58-year-old woman presented with recurrent angina and an anomalous right coronary artery originating from the left sinus. After repeated failures using conventional catheter selection, a 1:1 scale 3D-printed model was used for bench testing. This enabled the selection of an EBU 3.0 guiding catheter, leading to a successful PCI with 2 drug-eluting stents. DISCUSSION: This case demonstrates that 3D bench testing allows operators to anticipate support limitations and select optimal catheter geometry, potentially reducing procedure time and radiation. It highlights a structured alternative to empirical "trial-and-error" strategies in complex congenital anatomy. TAKE-HOME MESSAGE: Patient-specific 3D modeling facilitates successful PCI in AAOCA by enabling precise preprocedural simulation and optimal guiding catheter selection.
