The relative importance of arterial remodeling compared with intimal hyperplasia in lumen renarrowing after balloon angioplasty. A study in the normal rabbit and the hypercholesterolemic Yucatan micropig.

Abstract

In both the normal rabbit and the normal and atherosclerotic pig, restenosis after angioplasty results from both intimal hyperplasia and arterial remodeling. The exact etiology of arterial renarrowing after angioplasty has important implications on the design of antirestenosis drugs and new coronary devices.
