Observation of early strut coverage after polymer-free biolimus-a9 coated stent by optical frequency domain imaging

Yusuke Ochiumi, Yoriyasu Suzuki

An 80-year-old male patient with an acute myocardial infarction in the mid left anterior descending
artery was treated with a BioFreedom stent (2.5 × 24 mm). A month later, the patient was re-admitted
with chest pain. A significant coronary artery stenosis in the mid left anterior descending artery more
progressive than the previous one (not involving proximal stent-edge) was treated with percutaneous
coronary intervention. Then, optical frequency domain imaging of the Biofreedom stent revealed a
fully expanded stent with complete stent apposition in its entire length and strut coverage with
neointimal hyperplasia.
