Double kissing crush versus culotte for bifurcation percutaneous coronary interventions: insights from the PROGRESS-BIFURCATION registry.

Background: Upfront 2-stent techniques are often used in bifurcation percutaneous coronary interventions (PCI), but there is controversy about optimal strategy selection.
Methods: The authors examined the clinical and angiographic characteristics and long-term outcomes of 232 bifurcation PCIs that were performed using the double kissing (DK) crush or culotte technique in 216 patients between 2014 and 2023 using data from the Prospective Global Registry for the Study of Bifurcation Lesion Interventions (NCT05100992). The inverse probability of treatment weighted (IPTW) Cox proportional hazards model was used to assess long-term outcomes.
De Novo Atherosclerotic Renal Artery Stenosis Covered Stent Treatment for Resistant Hypertension (ARTISAN) Results.
J Soc Cardiovasc Angiogr Interv

The University of Toledo, Toledo, Ohio.
Background: Atherosclerotic renal artery stenosis (ARAS) may provoke hypertension and/or impaired kidney function. Some patients develop uncontrolled hypertension and deteriorating kidney function despite optimal medical therapy. In these patients, endovascular treatment is an important therapeutic option.

Intracranial atherosclerosis (ICAS) is a major cause of ischemic stroke, disproportionately affecting populations with significant vascular risk factors. Although ICAS imposes a considerable health burden, research on this condition in Central Asia remains scarce, especially among the Kazakh population. This study analyzes demographic characteristics, treatment outcomes, and procedural challenges associated with ICAS in 216 patients treated at a single institution.

Colorectal cancer (CRC) is a leading cause of cancer mortality, with many patients presenting with malignant colorectal obstruction (MCO). Self-expandable metal stents (SEMSs) have emerged as a minimally invasive key intervention, both as a bridge to surgery (BTS) in curative setting sand for palliation in advanced disease. This review aims to provide an evidence-based analysis of SEMS indications, contraindications, and efficacy across curative and palliative contexts, with focus on long-term outcomes.

Coated metallic stents are the next generation of metallic stents with improved surface properties. To evaluate the degradation behavior of stents in vitro, different in vitro degradation models can be applied: (i) static immersion test: degradation under static fluid condition, (ii) fluid dynamic test: degradation under flowing fluid, and (iii) electrochemical corrosion test: degradation under the influence of electric potential. During these experimental procedures, stents interact with the simulated blood plasma, and degradation products are formed in the form of depositions on the stent surface, likewise in vivo experiments.
