Late Coronary Ostial Stenosis After Complicated Bentall-De Bono Procedure: Multimodal Imaging Assessment.
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
backgroundCoronary ostial stenosis (COS) is a rare but potentially fatal complication following the Bentall-De Bono procedure. CASE SUMMARY: A 59-year-old man with prior Bentall-De Bono surgery along with venous graft reconstruction presented 8 years later with heart failure. Coronary computed tomography angiography demonstrated venous graft ostial stenosis, and cardiac magnetic resonance confirmed a transmural infarction with impaired ventricular function. Given the complex coronary anatomy and limitations to percutaneous treatment, the Heart Team opted for urgent surgical revascularization. DISCUSSION: COS after aortic root replacement results from multifactorial mechanisms, including surgical trauma, excessive tension, kinking, or fibrosis related to adhesives, whereas venous graft stenosis adds further complexity. Diagnosis is often challenging because coronary angiography may underestimate the disease while coronary computed tomography angiography and cardiac magnetic resonance offer superior anatomical and functional assessments, enabling accurate detection and guiding timely revascularization. TAKE-HOME MESSAGES: COS represents an uncommon yet life-threatening complication of aortic root replacement. Advanced multimodal imaging is pivotal to precise diagnosis and therapeutic guidance. Prompt, tailored revascularization strategies are essential to improving clinical outcomes.
