Recurrent STEMI After Surgical Aortic Valve Replacement.
Article in JACC. Case reports, 2025. 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
backgroundA 63-year-old man underwent surgical aortic valve replacement with an On-X valve using COR-KNOT suturing to facilitate a mini-sternotomy approach. CASE SUMMARY: The patient presented with recurrent inferior ST-segment elevation myocardial infarctions over a few-year period, despite optimal anticoagulation therapy. Repeated coronary angiography showed no obstructive coronary artery disease or thromboembolic occlusion. Intravascular ultrasound showed a filling defect in the ostium of the right coronary artery (RCA). A cardiac computed tomography confirmed the interference between a COR-KNOT and the RCA. Percutaneous coronary intervention of the RCA ostium was performed with good outcomes. DISCUSSION: This is the first case to report a ST-segment elevation myocardial infarction caused by an automated suturing. The combination of mini-sternotomy with COR-KNOT may have contributed to this rare but serious complication. TAKE-HOME MESSAGES: Multimodality imaging is crucial in establishing unusual diagnoses. COR-KNOT may interfere with coronary flow resulting in transient coronary occlusion when used in surgical aortic valve replacement.
