Late coronary BVS malapposition and aneurysm: A Time for Appraisal.

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.
