Overlapping bioresorbable scaffolds seems safe for now.

Overlapping permanent scaffolds carries a long-term risk of target vessel failure due to late malapposition and the development of neoatherosclerosis. Potentially, overlapping bioresorbable scaffold (BRS) may lead to lower long-term risk. The GHOST-EU registry reported similar short- and mid-term risks in patients with and without BRS overlap. Larger size studies with longer follow-up are needed to confirm the safety of BRS overlap.
