This article describes the stroke volume selection and operational design for the toroidal
ventricular assist device (TORVAD), a synchronous, positive-displacement ventricular assist …

Over the past two decades, left ventricular assist device (LVAD) support has emerged as
standard therapy for adult patients with advanced, life-threatening heart failure …

The biomechanics of the aortic valve are altered in patients with ventricular assist devices
(VADs). During high VAD flow and low cardiac function, transvalvular pressure is high, and …

There is evidence that the incidence of aortic valve incompetence (AI) and other valvular
pathologies may increase as more patients are submitted to longer periods of ventricular …

We are developing a universal, advanced ventricular assist device (AVAD) with automatic
pressure regulation suitable for both left and right ventricular support. The primary goal of …

Background Continuous-flow left ventricular assist devices (LVADs) cause blood trauma that
includes von Willebrand factor degradation, platelet activation, and subclinical hemolysis …

BACKGROUND: Left ventricular assist devices (LVADs) are an important therapy for
selected individuals with advanced heart failure unable to wait for a suitable donor for …

We report the first attempt to study with numerical methods ventricular assist device (VAD)
models and the effects of various inlet VAD cannulations, coupling physical explanations …

Hemodynamic performances comparisons between different types of left ventricular assist
devices (LVADs) remain difficult in a clinical context. The aim of this study was to create an …

Abstract Background The Advanced ventricular assist device (Advanced VAD) is designed
as a universal pump intended to prevent backflow in the event of pump stoppage, to …
