Aims: Limited data exist on radial access in carotid artery stenting (CAS). This single-center study was performed to compare the outcome and complication rates of transradial (TR) and transfemoral (TF) CAS.
Methods And Results: The clinical and angiographic data of 775 consecutive patients with high risk for carotid endarterectomy, treated between 1999 and 2016 by CAS with cerebral protection, were evaluated. Patients were divided into 2 groups according to vascular access: TR (n = 101; 13%) and TF (n = 674). Primary combined end-point: in-hospital major adverse cardiac and cerebral events. Secondary end-points: angiographic outcome of the procedure and crossover rate to another puncture site. Angiographic success was achieved in all 775 patients, the crossover rate was 4.9% in the TR and 0% in the TF group (P < 0.05). TR was performed at the right side in 97% of cases. The incidence of in-hospital major adverse cardiac and cerebral events was 2% in the TR and 3.6% in the TF group (P = ns).
Conclusions: The TR approach for CAS is safe and efficacious, with acceptable cross-over rate. In both groups, vascular complications rarely occurred.

Background: The triglyceride-glucose (TyG) index is now widely recognized as a marker of insulin resistance and has been linked to the development and prognosis of atherosclerotic cardiovascular diseases (ASCVD) in numerous populations, particularly in the Eastern world. Although there are fewer reports from the Western world, and they are sometimes contradictory, the absence of definitive data on the relationship between a raised TyG index and cardiovascular risk suggested the opportunity of testing this biochemical marker against a well-established vascular marker such as the carotid intima media thickness (c-IMT).
Methods: Primary prevention patients were selected from a cohort of individuals who underwent c-IMT measurement between 1984 and 2018 at the Dyslipidemia Center at the ASST Grande Ospedale Metropolitano Niguarda in Milan, Italy.

Extracellular matrix (ECM)-based small-diameter vascular grafts (SDVGs, inner diameter (ID) < 6 mm) hold great promise for clinical applications. However, existing ECM-based SDVGs suffer from limited donor availability, complex purification, high cost, and insufficient mechanical properties. SDVGs with ECM-like structure and function, and good mechanical properties were rapidly prepared by optimizing common materials and preparation, which can improve their clinical prospects.

Clarifying the inceptive pathophysiology of hypertensive heart disease helps to impede the disease progression. Through coarctation of the infrarenal abdominal aorta (AA), we induced hypertension in minipigs and evaluated physiological reactions and morpho-functional changes of the heart. Moderate aortic coarctation was achieved with approximately 30 mmHg systolic pressure gradient in minipigs.

Introduction: Atherosclerosis is the underlying cause of multiple cardiovascular pathologies. The present-day clinical imaging modalities do not offer sufficient information on plaque composition or rupture risk. A disintegrin and metalloproteinase with thrombospondin motifs 4 (ADAMTS4) is a strongly upregulated proteoglycan-cleaving enzyme that is specific to cardiovascular diseases, inter alia, atherosclerosis.
