OCT for bifurcations
• Coverage and Tissue bridges
• Deformation of struts in provitional strategy
– Deformation or strut fractures?
• Sustained effect or recoil of polymere backbone?
• Deformation in two stent/scaffold strategy

OCT of BVS in Bifurcations
• Strut coverage and neointima bridge occur
• Stent deformation happens like metallic stents
• Deformation remains over time
• Strut discontinuities not observed yet
• 2 Scaffold strategy possible
• 3D-OCT illustrative
