title: A coronary "tunnel": optical coherence tomography assessment after rotational atherectomy.
abstract: A 81-year-old woman was admitted for exertional angina. Coronary angiogram revealed a severely calcific proximal circumflex lesion. Rotational atherectomy was performed with 1.5 and 1.75 burrs, obtaining a good angiographic result. Optical coherence tomography (OCT) assessment revealed a large dissection parallel to the true lumen. We implanted a 3.0 mm × 38 mm Xience Prime(®) stent and postdilated it with a 3.0-mm non-compliant balloon. Final OCT pullback showed mild malapposed struts with large lumen area. 3D-OCT reconstruction confirmed a large lumen after stent implantation.
