No-Reflow Phenomenon During Treatment of Coronary In-Stent Restenosis With a Paclitaxel-Coated Balloon Catheter

Drug-eluting balloon (DEB) with angioplasty a paclitaxel-coated balloon catheter is an effective treatment option in patients with in-stent restenosis (ISR) after a drug-eluting stent (DES). We describe a case in which 'no-reflow' phenomenon developed after DEB angioplasty of a DES ISR lesion. Coronary flow was restored after intracoronary administration of nicorandil.
