Two-year Optical Coherence Tomography Findings after Balloon-Only Treatment of Bioresorbable Scaffold Restenosis in a Calcified Coronary Lesion: A Case Report.

We report a case of a 65-year-old female patient treated with an everolimus-eluting bioresorbable scaffold (BRS) after rotational atherectomy of a severely calcified lesion of the left anterior descending coronary artery. The implanted BRS restenosed 10 months after implantation and was treated with a scoring balloon followed by drug-eluting balloons with good immediate and long-term results. To the best of our knowledge, this is the first report of a balloon-only treatment of a restenosis occurring more than 6 months after BRS implantation; angiographic and optical coherence tomography images after treatment and at two-year follow-up are presented.
