The "Mushroom Sign": An Interesting Case Report of Extreme Stent Malapposition.
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
backgroundLate stent malapposition (LSM) is a recognized phenomenon that can lead to adverse clinical outcomes, including stent thrombosis and restenosis. Optical coherence tomography (OCT) offers high-resolution imaging, aiding in the diagnosis and management of LSM during complex percutaneous coronary interventions. CASE SUMMARY: A 65-year-old male patient with prior drug-eluting stent implantation in the right coronary artery presented for electrophysiological evaluation because of nonsustained ventricular tachycardia. Coronary angiography revealed mild in-stent restenosis and aneurysmal deformation of the right coronary artery. OCT demonstrated severe stent malapposition with a "mushroom sign," indicating positive vessel remodeling. The malapposed stent was crushed with a noncompliant balloon, followed by implantation of 2 new drug-eluting stents. Postprocedural OCT confirmed successful stent apposition and vessel restoration. DISCUSSION: This case underscores OCT's value in diagnosing LSM and guiding effective percutaneous coronary intervention in complex lesions. TAKE-HOME MESSAGE: OCT is indispensable for detecting LSM and optimizing stent placement, improving outcomes in complex coronary interventions.
