Late Thrombosis of First-Generation Bioresorbable Scaffold Site Treated With Novel Resorbable Magnesium Scaffold.

Background: To the best of our knowledge, this is the first reported experience of a patient with late thrombosis of previous Absorb (Abbott Vascular) bioresorbable scaffold (BRS) implantation site, treated with second-generation Magmaris (Biotronik) resorbable magnesium scaffold (RMS).

Case summary: A 55-year-old man with a previously implanted Absorb BRS stent presented with a non-ST-elevation myocardial infarction. Coronary angiography showed thrombotic lesion at the BRS stent site. After intravascular optical coherence tomography (OCT) imaging, a decision was made to implant a second-generation RMS stent. OCT follow-up was performed, with excellent long-term results.

Discussion: Randomized controlled trials have connected early BRS implantation to a higher rate of stent thrombosis. In recent years, the newer generation RMS has confirmed a good safety profile and long-term patency. The idea behind this treatment was to assess the novel RMS technology with serial OCT imaging.

Take-home messages: This case adds new options for the treatment of coronary arteries with novel RMS technology. Intravascular imaging with OCT is essential for optimized treatment and follow-up.
