Key result
Bioresorbable vascular scaffolds linked to late acquired strut malapposition and potentially lethal coronary aneurysms.
Why the study?
Little is known about late acquired struts malapposition of biovascular scaffolds despite its potential lethality.
Case Report (n=2)
Highlights the occurrence of late acquired strut malapposition and aneurysm with biovascular scaffolds as a potentially lethal complication.

May signal lethal late aneurysm risk with bioresorbable scaffolds; leaves open long-term safety questions.
Late strut malapposition of currently available stents is a major issue, associated with an increased risk of stent thrombosis. To this day, biovascular scaffolds showed an increased immediate risk of struts malapposition, that however resulted reduced after a few months. Little is known about late acquired struts malapposition of biovascular scaffolds. We here describe two cases that recently occurred in our patients, and we speculate on possible mechanisms for this unexpected and potentially lethal complication.

Cortese et al. (2014) conducted a case report in Late coronary BVS malapposition and aneurysm (n=2). Biovascular scaffolds was evaluated. Two cases of late acquired strut malapposition and aneurysm associated with biovascular scaffolds are described, highlighting a potentially lethal complication.
