Targeted myocardial gene expression in failing hearts by RNA sequencing
Background Myocardial recovery with left ventricular assist device (LVAD) therapy is highly variable and difficult to predict. Next generation ribonucleic acid (RNA) sequencing is an innovative, rapid, and quantitative approach to gene expression ...

Risks and Benefits of Using a Commercially Available Ventricular Assist Device for Failing Fontan Cavopulmonary Support: A Modeling Investigation [PDF]
Fontan patients often develop circulatory failure and are in desperate need of a therapeutic solution. A blood pump surgically placed in the cavopulmonary pathway can substitute the function of the absent sub-pulmonary ventricle by generating a mild pressure boost.

Automated CFD shape optimization of stator blades for the PediaFlow pediatric ventricular assist device [PDF]
PediaFlow is a miniature mixed-flow ventricular assist device for neonates and toddlers. PediaFlow has a fully magnetically levitated rotor which improves biocompatibility, but the increased length of the rotor creates a long annular passage where fluid energy is lost.

Experience with left ventricular assist device usage in the treatment of end-stage heart failure [PDF]
Heart failure potentially developing in most of heart diseases is a progressive process associated with high morbidity and mortality. Almost 3/4 of patients die within five years after first hospitalization because of heart failure.
