Abstract
BACKGROUND Although Medina 0.0.1 bifurcation lesions are often treated by percutaneous coronary intervention (PCI) in real-world practice, the optimal revascularization strategy for this lesion is uncertain. OBJECTIVES The current study aimed to compare the clinical outcomes between 1- and 2-stent strategies in patients treated with PCI for Medina 0.0.1 bifurcation lesions. METHODS The extended BIFURCAT (Combined Insights From the Unified RAIN [Very Thin Stents for Patients with Left Main or Bifurcation in Real Life] and COBIS [Coronary Bifurcation Stenting] Bifurcation Registries) registry was obtained by patient-level merging the dedicated bifurcation COBIS II, III, and RAIN registries. Among 8,434 patients with bifurcation lesions undergoing PCI, 345 (4.1%) with Medina 0.0.1 lesions were selected for the current analysis. The primary endpoint was major adverse cardiac event (MACE, a composite of all-cause death, myocardial infarction, target vessel revascularization, and stent thrombosis) at 800 days. RESULTS In the total population, 209 patients (60.6%) received PCI with a 1-stent strategy and the remaining 136 patients (39.4%) with a 2-stent strategy. There was a tendency for higher use of a 1-stent strategy over time (36.0%, 47.4%, and 90.4% in 2003-2009, 2010-2014, and 2015-2017, respectively; P for trend < 0.001). For the treatment of Medina 0.0.1 lesions, there was no significant difference in the risk of MACE between 1- and 2-stent strategies (1 stent vs 2 stent, 14.3% vs 13.9%; HR: 1.034; 95% CI: 0.541-1.977; P = 0.92). The risk of MACE was also not significantly different when stratifying into 3 groups (1-stent crossover only, 1-stent with strut opening, and 2-stent strategy). CONCLUSIONS In patients with a Medina 0.0.1 type bifurcation lesion, PCI with a 1-stent strategy showed comparable outcomes to that of a 2-stent strategy.

Abstract
BACKGROUND Wall shear stress (SS) plays an important role in the initiation and proliferation of coronary atherosclerosis, especially for bifurcations. Stenting in the coronary artery will cause many different changes in velocity, flow, cross-sectional area, and especially the wall SS. However, it is still unknown how much wall SS distribution varies with stenting in coronary bifurcation. OBJECTIVE The purpose of this study was to investigate the magnitude and distribution of wall SS after the classical crush stenting for bifurcation lesions. METHODS Eleven patients with true coronary bifurcation stenting by the classical crush technique were included. We studied the difference of wall SS between restenosis and nonrestenosis groups in these patients. The differences in SS between preprocedure and postprocedure, as well as between immediately postprocedure and after an 8-month follow-up, were also analyzed. Diameter stenosis or minimal lumen diameter were measured by quantitative coronary analysis. The commercial CD STAR-CCM+ was used to calculate the SS. RESULTS At baseline, the SS in all the segments of all patients was high. The baseline SS of the restenosis group was 50% lower than the nonrestenosis group. Immediately after percutaneous coronary intervention (PCI), the SS in both areas decreased; however, the SS of the nonrestenosis group decreased to its lowest level possible while the SS of the restenosis group decreased moderately. Eight months later, the SS of all the segments of the nonrestenosis group remained persistently low at the same level of right after PCI. In contrary, the SS in the restenosis group returned to near its baseline level. CONCLUSION From our study, after a 2-stent crush technique using drug-eluting stents (DES), the degree of SS reduction appears to predict in-stent restenosis (ISR). A SS decrease to its lowest level and remaining homogenously low is a prime condition to prevent ISR. A baseline low SS, which decreases minimally after PCI and recovers to around its baseline level, appears to be the setting for restenosis. These conditions can be evaluated as predictors of lesions that may need surveillance angiography and proper IVUS evaluation to prevent future in-stent restenosis.
