Bioresorbable vascular scaffolds (BVSs) represent the newest tool in the treatment of coronary artery disease (CAD). Conversely to the previous metal stents and thanks to the polylactate-based backbone, BVSs could be visualized by magnetic resonance imaging (MRI) without artifacts. These properties allow a potential non-invasive assessment of coronary artery patency after percutaneous coronary intervention (PCI), avoiding cardiac catheterization included iodine contrast and radiation exposure, and potentially more sophisticated imaging tool as the optical coherence tomography (OCT). We reviewed the available medical literature on the coronary MRI evaluation of BVS after PCI, also discussing its potential diagnostic role in the long-term follow-up of these patients.
生物可吸收血管支架（BVS）是治疗冠状动脉疾病（CAD）的最新工具。与以往的金属支架不同，由于其基于聚乳酸的骨架，BVS可通过磁共振成像（MRI）进行可视化且无伪影。这些特性使得在经皮冠状动脉介入治疗（PCI）后对冠状动脉通畅情况进行潜在的非侵入性评估成为可能，避免了包括碘造影剂和辐射暴露的心脏导管插入术，以及像光学相干断层扫描（OCT）这样可能更复杂的成像工具。我们回顾了关于PCI后BVS的冠状动脉MRI评估的现有医学文献，同时也讨论了其在这些患者长期随访中的潜在诊断作用。
