The coronary artery disease (CAD) is rapidly increasing such as angina pectoris and atherosclerosis. The CAD is induce by cholesterol and calcium like plaque absortion to artery wall. The percutaneouss coronary intervention is non-invasive treatment that narrowed-artery is expand by using balloon catheter and bare metallic stent. The metallic stents have been effective in reducing the dead by coronary artery disease, but the permanent presence of the metallic stent has been associated with persistent inflammation, and incidence of late thrombosis. Therefore, development bioresorbable vascular scaffold (BRS) is rapidly increasing for treatment of long-term complications and arterial restenosis by permanentmetal prosthesis such as stent. The review discusses the BRS trend for successfully development.
