Late coronary stent thrombosis can manifest as acute myocardial infarction 19 months after stenting, even without prior clinical symptoms or angiographic restenosis.

Late coronary stent thrombosis can occur long after stenting (19 months) without prior brachytherapy or angiographic restenosis, presenting as acute myocardial infarction.
Clinicians should consider very late stent thrombosis in unexplained post-stent AMI; case reports leave optimal DAPT duration open.
A 63-year-old Japanese man was readmitted to our hospital due to acute broad-anterior myocardial infarction (AMI). The proximal left anterior descending artery (LAD) at the prior stent, which was implanted 19 months earlier and in which no angiographic restenosis was recognized 13 months before the second study, was totally occluded. After crossing a guide wire and balloon angioplasty, angiographic radiolucency was observed at the prior stent, suggesting that AMI was induced by late coronary stent thrombosis. Intravascular ultrasound performed 19 days after the onset of AMI revealed superficial calcification without significant stenosis and an atherosclerotic plaque distal to the stent that was not significantly changed compared to 19 months previously, consistent with the culprit lesion being an intrastent site. AMI may thus be induced by late coronary stent thrombosis during long-term clinical follow-up without clinical symptoms or angiographic restenosis at the second study.

Ishikawa et al. (2004) conducted a case report in Late coronary stent thrombosis (n=1). Coronary stenting was evaluated on Late coronary stent thrombosis. Late coronary stent thrombosis can manifest as acute myocardial infarction 19 months after stenting, even without prior clinical symptoms or angiographic restenosis.
