Practical concerns regarding poly-L-lactic acid (PLLA)-based bioresorbable scaffolds (BRS) are mostly related to the strut thickness of 150 µm. Implantation may cause more vessel injury as well as non-laminar flow and activation of platelet function. Furthermore, constraints of deliverability preclude BRS use in the presence of tortuosity or severe calcification. The PLLA-based novolimus-eluting DESolve® 100 scaffold (Elixir Medical Corporation, Sunnyvale, CA, USA) has a strut thickness of 100 µm. Complete degradation is achieved within two years. Furthermore, it has wider expansion ranges than other BRS and self-correction properties corresponding to nominal diameters, which can resolve minor malapposition.

In a mid-RCX stenosis, ...
