A 79-Year-Old Man with a History of Ischemic Heart Disease Presenting with Right Coronary Artery Aorto-Ostial Stent Deformity and Restenosis: A Case Report.

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
BACKGROUND Ostial right coronary artery (RCA) involvement is a relatively uncommon location for coronary artery disease and requires consideration of anatomic factors (aortic root involvement) and potential increased recoil. This makes stent placement prone to a geographic miss, especially in the context of limitations associated with two-dimensional coronary angiography. Moreover, the design of newer stent generations, which allows for easier deliverability but with increased susceptibility to mechanical damage, may place them at increased risk for longitudinal deformity when deployed in the right coronary ostium. This report describes the case of a 79-year-old man with a history of ischemic heart disease presenting with RCA aorto-ostial stent deformity and restenosis. CASE REPORT The patient presented with acute-onset ischemic chest pain and was found to have non-ST-elevation myocardial infarction (NSTEMI). Coronary angiography revealed significant 2-vessel coronary artery disease involving the mid-portion of the left anterior descending artery and the ostium of the RCA. The latter was due to associated in-stent restenosis of an overhanging stent protruding into the aorta. The patient underwent coronary artery bypass graft surgery with removal of the displaced stent, which was found to have evidence of a longitudinal deformity in its middle portion. CONCLUSIONS This report highlights a rare but important complication of the use of coronary artery stents, particularly when used in the region of the RCA ostium, and the management of stent deformity and restenosis.
