Early Restenose in a Polymer-Free Biolimus A9-coated Stent (BioFreedom): a Case Report based on Optical Coherence Tomography

A 81year old male patient with a severe de novo coronary artery stenosis in the proximal left anterior descending artery was treated with a BioFreedom stent (3.5 ×11mm), three months later, the patient was re-admitted with chest pain and slightly increased troponin. The angiogram showed a significant in-stent restenosis in the recently treated lesion. Optical coherence tomography revealed a fully expanded stent without areas of incomplete stent apposition. Severe immature neointimal hyperplasia without formation of thrombosis was visualized, causing a severe in-stent restenosis.
