Comparison of acute versus stable coronary syndrome in patients treated with the Magmaris scaffold: Two-year results from the Magmaris Multicenter Italian Registry.

ABSTRACT

BACKGROUND: The magnesium Magmaris scaffold is the latest resorbable technology with low thrombogenicity, short scaffolding time, and almost complete resorption at 12 months (95 %). As compared with stable coronary artery disease (SCAD), acute coronary syndrome (ACS) is associated with increased risk of adverse clinical outcome after percutaneous coronary intervention. We analyzed the data of the Magmaris Multicenter Italian Registry to compare clinical outcomes in SCAD versus ACS patients. METHODS: We evaluated the 24-month rates of target lesion failure (TLF) and scaffold thrombosis (ST). Device implantation procedures were performed according to the manufacturer's recommendations (proper patient/lesion selection, pre-dilatation, proper scaffold sizing, and post-dilatation). Dual antiplatelet therapy was terminated after 12 months. RESULTS: Data from 207 patients (145 SCAD and 62 ACS) were collected from July 2016 to June 2018. The 2-year follow-up compliance was 92.8 % (192 patients). At 2 years, TLF rates were 7.4 % in the SCAD group and 8.8 % in the ACS group (p = 0.7); ST rates were 0 % in the SCAD group and 1.8 % in the ACS group (p = 0.1). CONCLUSION: The 2-year clinical results from the Magmaris Multicenter Italian Registry are favorable in terms of TLF and ST, indicating the safety and effectiveness of the Magmaris scaffold in both SCAD and ACS patients.
