The percutaneous treatment of coronary bifurcation stenoses is hampered by an increased rate of subsequent restenosis. The present study reports on the outcomes of a consecutive series of 58 patients with 65 de novo bifurcation stenoses treated with sirolimus-eluting stent implantation in both the main vessel and side branch. At 6 months, the incidence of major adverse cardiac events was 10.3% (1 death and 5 target lesion revascularizations) with no episodes of acute myocardial infarction or stent thrombosis.

The outcomes of bifurcation percutaneous coronary intervention (PCI) in patients aged ≥80 and ≥90 years have received limited study. We compared the procedural characteristics and outcomes of bifurcation PCIs in patients aged ≥80 years and those aged <80 years in a multicenter registry. Of 1,253 patients who underwent 1,262 bifurcation PCIs between 2014 and 2024 at 6 centers, 194 (15%) were aged ≥80 and ≥90 years.

Background And Objectives: The risk profiles, procedural characteristics, and clinical outcomes for women undergoing bifurcation percutaneous coronary intervention (PCI) are not well defined compared to those in men.
Methods: COronary BIfurcation Stenting III (COBIS III) is a multicenter, real-world registry of 2,648 patients with bifurcation lesions treated with second-generation drug-eluting stents. We compared the angiographic and procedural characteristics and clinical outcomes based on sex.

The impact of diabetes mellitus (DM) on the outcomes of bifurcation percutaneous coronary intervention (PCI) has received limited study. We compared the procedural characteristics and outcomes of patients with and without DM in 1,302 bifurcation PCIs (1,147 patients) performed at 5 centers between 2013 and 2024. The prevalence of DM was 33.

The strong link between atherosclerosis and luminal biomechanical stresses is well established. Yet, this understanding has not translated into preventative coronary diagnostic imaging, particularly due to the under-explored role of coronary anatomy and haemodynamics in plaque onset, which we aim to address with this work. The left coronary trees of 20 non-stenosed (%diameter stenosis [%DS] = 0), 12 moderately (0 < %DS < 70) and 7 severely (%DS ≥ 70) stenosed cases were dissected into bifurcating and non-bifurcating segments for whole-tree and segment-specific comparisons, correlating nine three-dimensional coronary anatomical features, topological shear variation index (TSVI) and luminal areas subject to low time-average endothelial shear stress (%LowTAESS), high oscillatory shear index (%HighOSI) and high relative residence time (%HighRRT).

Background: With the popularization of various cerebrovascular imaging methods and increased attention to the field, more cerebrovascular diseases are being detected in asymptomatic patients. Different cerebrovascular diseases are typically isolated but occasionally occur simultaneously, causing difficulties in diagnosis and treatment. Morphological changes in the collateral circulation of blood vessels in chronic cerebral artery occlusion patients are slow and dynamic, intercepting morphological development at a specific moment.
