Centrifugal Ventricular Assist Devices
AACN Advanced Critical Care, 1991A centrifugal ventricular assist device (VAD) uses centrifugal force to propel blood through nonocclusive pumpheads. Blood is diverted from either the right atrium or left atrium to a disposable pumphead. Then kinetic energy is added to blood contained within the VAD by rotating it at high speed.

Ventricular Assist Devices and Anesthesia
Seminars in Cardiothoracic and Vascular Anesthesia, 2005Ventricular assist devices (VADs) have revolutionized longterm care for patients with congestive heart failure. These patients represent about 1% of the adults in the United States, considering that heart failure is a contributing factor in more than 250,000 deaths annually. It has been estimated that about 60,000 patients per year in the United States

Are Ventricular Assist Devices Underutilized?
Journal of Cardiac Surgery, 2010A dramatic shift in the durability and reliability of ventricular assist device (VAD) therapy is taking hold due to the newer generations of continuous flow VADs that are either in clinical trials or under consideration by the Food and Drug Administration (FDA) for commercial approval. To expand the pool of potential mechanical circulatory support (MCS)

Ventricular Tachycardia in the Era of Ventricular Assist Devices
Journal of Cardiovascular Electrophysiology, 2010Sustained ventricular tachycardia (VT) in patients with advanced cardiomyopathy is a potentially life-threatening arrhythmia. Newer treatment strategies have evolved that combine the use of catheter ablation to target the substrate for VT and ventricular assist devices (VADs) to hemodynamically support the failing ventricle.

Ventricular Assistance Devices as Bridge to Transplantation
Heart Failure Clinics, 2014The authors herein review the rationale and indications for the use of ventricular assistance devices as a bridge to heart transplantation and discuss the current evidence on the subject. The potential effects of device implantation on posttransplant outcomes and the therapeutic strategies in acute and elective cases are revised and illustrated.

Left ventricular assist devices
Heart, 2009Left ventricular assist device (LVAD) insertion in patients with advanced heart failure with deteriorating clinical status is life saving, and LVADs are now being inserted into an increasing number of patients with advanced heart failure. They were initially inserted as a bridge to transplantation, and the decreased availability of donor hearts means ...

Hydrodynamic Characterisation of Ventricular Assist Devices
The International Journal of Artificial Organs, 2001A new mock circulatory system (MCS) was designed to evaluate and characterise the hydraulic performance of ventricular assist devices (VADs). The MCS consists of a preload section and a multipurpose afterload section, with an adjustable compliance chamber (C) and peripheral resistor (R p ) as

Demystifying Ventricular Assist Devices
Critical Care Nursing Quarterly, 2011Many people throughout the world are living with heart disease and advanced heart failure. They may be in need of a heart transplant, but because of the limited amount of donor hearts available, other options need to be available. Because of the advancement of technology, there are now other options, and one option available would be a mechanical ...
