Efficacy of coronary angioplasty with a cutting balloon in a case of repeated coronary stenosis.

Abstract

A 59-year-old man with a 90% stenosis of the left anterior descending coronary artery was treated with percutaneous transluminal coronary angioplasty (PTCA) using a conventional balloon. The stenosis recurred repeatedly and was retreated by PTCA three times. The stenosis again recurred, so coronary angioplasty using a cutting balloon was performed. During the present admission, we planned to place a coronary stent in the LAD to prevent restenosis. Anticoagulation is necessary after coronary stenting. However, anticoagulation was contraindicated in this patient because of ulcerative colitis. Therefore, coronary angioplasty using a cutting balloon was performed instead. The stenosis decreased from 90% to 25%, but a coronary dissection occurred. An angiogram performed 3 months later showed no stenosis, with resolution of the coronary dissection. The use of a cutting balloon preventing coronary artery restenosis following balloon angioplasty is a promising new technique which warrants further study.
