title: Minimally invasive atherectomy with a virtual 3-Fr sheathless guiding catheter and a 0.9-mm excimer laser catheter for the treatment of coronary in-stent restenosis: a case report.
abstract: A 50-year-old man underwent percutaneous coronary intervention for stent restenosis in his left anterior descending artery. After insertion of a 5-Fr sheathless guiding catheter through the right radial artery, optical coherence tomography (OCT) revealed a circumferential dense fibrotic plaque in the distal part of the stent. Therefore, we performed excimer laser coronary atherectomy using a 0.9-mm concentric catheter and dilatation with a drug-coated balloon catheter. Subsequent OCT revealed a circumferential reduction of the neointimal material. The patient's clinical course was uneventful, and he was discharged 2 days after the percutaneous coronary intervention without any access site complications.
