Representative one case of optical coherence tomography (OCT) guided rotational atherectomy (RA) images. A Pre-PCI OCT images showed heavily calcified plaque with a 360° calcium arc and a minimal calcium thickness of 0.65mm. B After RA with a 1.5-mm burr, the calcium thickness measured 0.61mm without crack formation. The operator decided to upsize the burr. C After additional atherectomy with a 1.75-mm burr, the calcium thickness became 0.40mm with cracks formation. D After stent implantation with post-dilatation OCT images showed adequate stent expansion (86%)
