Comparative Analysis of Three Different Optimization Procedures for Coronary Bifurcation Provisional Stenting: Insights from Micro-Computed Tomography and Optical Coherence Tomography Imaging of Bench Deployments

Background Post-dilation with kissing balloon dilation remains controversial in the 1-stent approach, but many technical improvements are possible to refine the final results. This study aimed to evaluate the results of different side-branch (SB) ostial treatments after main vessel stenting, including ostial optimization technique (OOT), simultaneous kissing balloon dilation (KBD) and single balloon dilation (SBD).
