Professor Patrick Serruys gives a comprehensive and unique insight into some of the intracoronary imaging results seen in an ABSORB-II substudy
- Objective: to confirm that Absorb bioresorbable scaffold has more potential to exhibit vessel remodeling than Xience metallic stents
- Overview of factors predicting expansive remodelling in arteries, treated either with Absorb or Xience
- Lesions treated with Absorb exhibited frequently larger increase in mean vessel area and lumen area than lesions treated with Xience
- Absorb implantation, female gender, expected balloon-artery ratio ≥ 1.25, expansion index ≥ 0.8, previous PCI, and higher mean level of LDL cholesterol (average over 3 years) were independent factors predicting expansive remodeling.
