The biodegradable ABSORB scaffold is characterized by a greater strut thickness, but it has a greater flexibility compared to the XIENCE stent. Due to its fragility the inflating pressure of the ABSORB scaffold is limited and suitable lesions have to be well prepared. This study assesses the incidence of malapposed stent-struts, and the frequency of stent-underexpansion and edge dissection after ABSORB implantation compared to the XIENCE stent.
