Aims: We aimed to assess the safety and performance of the Magmaris bioresorbable magnesium scaffold in a large patient population.

Methods and results: BIOSOLVE-IV is an international, single arm, multi-center registry. This is the pre-defined report on 12-month outcomes of the first 400 out of 2054 patients planned. Mean patient age was 62.0±11.0 years and 15.8% (n=63) had non-ST-elevation myocardial infarction. Lesions (n=425) were 3.3±0.3 mm in diameter and 14.5±4.1 mm long. The primary endpoint, target lesion failure at 12 months, occurred in 4.3% [95%CI:2.7;6.9], consisting of 4.3% target lesion revascularizations, 0% cardiac death, and 0.8% target-vessel myocardial infarction. One definite scaffold thrombosis occurred on post-procedure day 10 after cessation of dual antiplatelet therapy.

Conclusions: The preliminary analysis of the first 400 patients enrolled in BIOSOLVE-IV confirms the safety and performance of the Magmaris scaffold in clinical routine.
