title: The impact of Rho-kinase inhibitor, "Fasudil", intracoronary bolus administration to improve refractory coronary vasospasm.
abstract: A 57 year-old man presenting with acute inferior myocardial infarction underwent percutaneous coronary intervention. Following the placement of TAXUS Liberte 2.5 × 24 mm (Boston Sientific, USA), for 99% stenosis with delay, severe vasospasm occurred at distal portion of the stent. However, persistent vasospasm was observed despite ISDN (isosorbide dinitrate), nitroprusside, and nicorandil, were used to control the repetitive vasospasm during the course of 90 min. Then the decision was made to use intra-coronary bolus of Rho-kinase inhibitor, fasudil 100 μg/kg. Then the vasospasm resolved and no recurrence was observed during the procedure and hospital stay for 25 days. We experienced a valuable case, whose repetitive vasospasm was resolved with intracoronary administration of Rho kinase inhibitor.
