ABSTRACT Background Percutaneous femoral access serves as the cornerstone of endovascular therapy of lower extremity arterial disease. In complex cases, the arterial disease of lower extremity are involve in ipsilateral iliac artery pathology, which conventional treatment strategies typically require multiple punctures or staged procedures.

Subcoronary versus supracoronary aortic stenosis. an experimental evaluation
Background Valvular aortic stenosis is the most common cause of left ventricular hypertrophy due to gradually increasing pressure work. As the stenosis develop the left ventricular hypertrophy may lead to congestive heart failure, increased risk of ...

Non-linear finite element analyses of the aortic heart valve
Includes bibliographical references.Finite element models of the aortic heart valve have been successfully used in the past to gain insight into the mechanics of the valve and to aid in understanding of valve failure.

LES of non-Newtonian physiological blood flow in a model of arterial stenosis [PDF]
Large Eddy Simulation (LES) is performed to study the physiological pulsatile transition-to-turbulent non-Newtonian blood flow through a 3D model of arterial stenosis by using five different blood viscosity models: (i) Power-law, (ii) Carreau, (iii ...

ABSTRACT Background Hybrid stage I palliation (HS1P) has developed as an alternative to the Norwood stage I palliation for neonates with hypoplastic left heart and related left‐sided obstructive lesions. HS1P is currently used in various clinical settings, such as single ventricle palliation, bridge to decision, bridge to biventricular repair, or ...
