The interventional cardiologist must be able to recognize and manage potential vascular complications. Iliofemoral complications are the most frequent vascular complications in transfemoral transcatheter aortic valve implantation. Small vessel dimensions, moderate or severe calcification, and center experience are the major predictors. The traditional treatment for injured arteries has been surgical ...

We hypothesize that after implantation the much elevated water filtration rate of venous grafts may cause aggravated concentration polarization of low density lipoproteins (LDLs), in turn lead to the accelerated atherogenesis of the grafts. To verify the hypothesis, we numerically simulated the transport of LDLs in various models of arterial ...

Untreated large vessel occlusions lead to high rates of mortality and morbidity in ischemic stroke. The 'recanalization hypothesis' posits that timely restoration of flow in the ischemic area leads to improved clinical outcomes by salvaging the underperfused and threatened tissue (penumbra). Intravenous thrombolysis is the first-line treatment for reperfusion but ...

Trans-aortic valve replacement is a new endovascular procedure which has started to be used routinely in cardiac interventional suites. During such procedures a stent-like device containing new aortic valves is placed over the damaged ones, possibly causing calcifications to be dislodged and released in arteries leading to stroke. To prevent ...

The prevalence of abdominal aortic aneurysms (AAAs) and AAA-related deaths are steadily declining in some countries as a result of the reduction in smoking rates. It was thus suggested that screening programs that do not target high-risk populations are likely to have very low AAA detection rates. However, this may ...
