CTICasesAcute Myocardial Infarction due to In-Stent Restenosis

Imaging findings
CT shows a hypoenhancing area in the posterior wall/septum, consistent with acute right coronary artery infarct. The RCA stent appears stenotic or occluded at its origin. Coronary angiogram confirms complete occlusion at the stent origin, which was successfully re-opened with intervention.
Key takeaways
CT can detect acute myocardial infarction as hypoenhancing myocardial regions. In-stent restenosis can lead to acute coronary occlusion and MI. This case highlights a scenario where a patient might have experienced an acute cardiac event leading to a fall.
