The study assessed the results of using 2-stent techniques in patients with complex coronary bifurcation lesions undergoing percutaneous coronary intervention (PCI) and evaluated factors that could lead to suboptimal results. The study was conducted in an experimental environment (Visible Heart Laboratories) using beating swine hearts. Microcomputed tomography (micro-CT) was used to assess the post-PCI stent configuration. The study found that suboptimal stent implantation was observed in 53.7% of cases, regardless of baseline anatomy or the stenting strategy. However, less frequent use of proximal optimisation technique (POT) and kissing balloon inflations (KBI), and no adherence to European Bifurcation Club (EBC) recommendations were significantly associated with suboptimal stent implantation.
