Influence of the arterial elastic component on the response to balloon angioplasty in femoral arteries of a healthy porcine model

Animal Models and Experimental Medicine, EarlyView.
This study evaluates the role of elastin in vascular response 28 days after balloon angioplasty using uncoated and paclitaxel‐coated balloons in a healthy porcine model. The results show higher elastin content in external femoral arteries, which is inversely correlated with vascular injury, inflammation, smooth muscle cell loss, proteoglycan and fibrin

Endovascular Treatment of Malfunctioning Dialysis Fistulas: A Multicenter Retrospective Analysis Comparing Transradial and Conventional Transvenous Access

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Venous outflow is the favored access for endovascular management of dialysis fistulas. However, transradial access (TRA) offers advantages in specific clinical scenarios. The study aims to compare the efficacy, feasibility, and safety of TRA and transvenous access (TVA) in the endovascular management of malfunctioning dialysis ...

Fractional Flow Reserve Directed Percutaneous Coronary Intervention Optimization Using High‐Definition Intravascular Ultrasound in Non‐ST‐Segment Elevation Acute Coronary Syndrome Versus Chronic Coronary Syndrome

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Intravascular ultrasound (IVUS)‐guided optimization of suboptimal fractional flow reserve (FFR) following percutaneous coronary intervention (PCI) results in a significant increase in both post‐PCI FFR and minimal lumen and stent areas (MLA and MSA, respectively).
