Key result
At 6 months, sirolimus-eluting stents evaluated by OCT showed a median neointima thickness of 52.5 μm and an 89% average rate of covered struts, though only 16% of stents had full coverage.

OCT assessment reveals mostly incomplete coverage on sirolimus-eluting stents at 6 months; leaves open whether this informs DAPT duration or thrombosis risk.
Observational (n=34)
OCT can detect thin neointimal coverage on sirolimus-eluting stents at 6 months that is undetectable by IVUS, revealing that most stents are covered with thin neointima but few have full coverage.
Matsumoto et al. (2006) conducted an observational in Patients with sirolimus-eluting stents (n=34). Sirolimus-eluting stents was evaluated on Neointima thickness and strut coverage evaluated by OCT. At 6 months, sirolimus-eluting stents evaluated by OCT showed a median neointima thickness of 52.5 μm and an 89% average rate of covered struts, though only 16% of stents had full coverage.
