Coronary accordion effect mimicking coronary dissection in a 41-year-old male during angiography procedure an interesting case report.
Article in Radiology case reports, 2024. 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
The accordion phenomenon is a rare pseudo-complication observed during percutaneous coronary intervention (PCI), which can mimic coronary dissection, spasm, or thrombus formation. Here we present a patient with inferior ST-segment elevation myocardial infarction (STEMI), who developed multiple pseudo lesions in the tortuous right coronary artery (RCA) during PCI. An emergency coronary angiography was performed, but unfortunately, the lesion developed into an accordion-like shape in the middle segment of the right coronary artery (RCA), which looked like a coronary dissection. Despite attempts to resolve the abnormality with intracoronary nitrates, the accordion effect persisted, leading to a drop in blood pressure. Subsequent administration of isotonic solution and additional intracoronary nitrates eventually alleviated the dissection pattern. Due to the small diameter of the posterior descending artery, balloon angioplasty was performed to complete the procedure successfully. The patient was discharged 2 days later with a prescribed regimen of aspirin, prasugrel, atorvastatin, and carvedilol. Follow-up after 1 week indicated the patient's well-being, with no reported complaints.
