A Multicenter, Randomized Trial of Coronary Angioplasty Versus Directional Atherectomy for Patients With Saphenous Vein Bypass Graft Lesions

Abstract

Atherectomy of de novo vein graft lesions was associated with improved initial angiographic success and luminal diameter but also with increased distal embolization. There was no difference in 6-month restenosis rates, although primary atherectomy patients tended to require fewer target-vessel revascularization procedures.
