Purpose: Deposition of plaque along the walls of a coronary artery leads to narrowed vessels (stenosis) and is one of the main causes of death in developed countries. Percutaneous transluminal coronary angioplasty is a treatment modality used to open the blocked arteries allowing unobstructed blood flow to the myocardium. However, the treated vessel may become narrow again. The event is referred to as restenosis. Restenosis can be prevented with the advent of bare metal stents; however, expanding a stent inside a vessel will subject the artery to high stresses that can injure the tissue, potentially leading to in-stent restenosis (ISR).
