title: Coronary artery perforation at the level of two-overlapping bioresorbable vascular scaffolds: The importance of vessel sizing and scaffold thickness.
abstract: Everolimus-eluting bioresorbable vascular scaffolds (BVS) have emerged as an alternative to conventional metallic stents and have demonstrated favorable outcomes in simple coronary lesions. As the use of BVS increases and extends to more complex lesion subsets, intraprocedural complications are expected to occur. We describe for the first time the occurrence of a free coronary perforation localized at the exact point of overlap of two BVS. This case illustrates the importance of appropriate vessel sizing, especially when BVS overlapping is performed in a small vessel, and potential advantages of scaffold juxtaposition compared to overlapping when implanting BVS in series.
