A Comparison of Directional Atherectomy with Coronary Angioplasty in Patients with Coronary Artery Disease

Abstract

Removing coronary artery plaque with atherectomy led to a larger luminal diameter and a small reduction in angiographic restenosis, the latter being confined largely to the proximal left anterior descending coronary artery. However, atherectomy led to a higher rate of early complications, increased cost, and no apparent clinical benefit after six months of follow-up.
