The implantation of bioresorbable Vascular Scaffolds (BVS) is a rapidly evolving technique in the treatment of coronary artery disease. BVS consist of a polylactate-based backbone which is completely dissolved after 2-3 years. Due to the organic material, coronary MRI can be used as a non-invasive technique for post-interventional imaging of arteries treated with BVS, which is not possible for metal stents. In this study, we evaluated the use of 3T MRI in assessing luminal patency after implantation of the BVS, as well as flow measurements for myocardial blood flow quantification as a possible indicator of post-interventional angina.
