Covalent surface modification of a titanium alloy with a phosphorylcholine-containing copolymer for reduced thrombogenicity in cardiovascular devices.

29 Sep 2009 Our objective was to develop a surface modification strategy for a titanium alloy (TiAl6V4) to provide thromboresistance for surfaces in rigorous blood-contacting cardiovascular applications, such as that found in ventricular assist devices. We ... Read more...

Heartmate II axial-flow left ventricular assist system: management, clinical review and personal experience.

29 Sep 2009 OBJECTIVES: The excellent results with left ventricular assist devices (LVADs) have revolutionized the treatment options for end-stage heart failure. The use of pulsatile devices is associated with significant comorbidity and limited durability. The ... Read more...

Does the need for noncardiac surgery during ventricular assist device therapy impact clinical outcome?

29 Sep 2009 BACKGROUND: The role of the ventricular assist device (VAD) in the management of heart failure is expanding. Despite its success, the clinical course for patients requiring noncardiac surgery (NCS) during VAD support is not well described. The ... Read more...

Technical information about 'Heart-Assist Devices'

Definition: Small pumps, often implantable, designed for temporarily assisting the heart, usually the left ventricle, to pump blood; they consist of a pumping chamber and a power source, which may be partially or totally external to the body and activated by electromagnetic motors; the devices are used after myocardial infarction or to wean the repaired heart from the heart-lung machine after open-heart surgery.
