Ventricular Assist Devices in Pediatric Cardiac Surgery

The Annals of Thoracic Surgery, 1995
Early experience in other centers with pediatric assist devices has been favorable.Prospectively we examined our first 13 patients between January 1992 and September 1994.Thirteen children underwent ventricular assistance at Royal Alexandra Hospital for Children. Age ranged from 4 days to 30 months, weight from 2.9 kg to 17 kg.

The Ventricular Assist Device as a Bridge to Cardiac Transplantation [PDF]

open access: possibleAACN Clinical Issues: Advanced Practice in Acute and Critical Care, 1999
Congestive heart failure is occurring in the United States at an increasing rate. Transplantation remains the treatment of choice for end-stage heart failure. Prolonged waiting time and decreased availability of suitable organs has increased the necessity for a device to act as a bridge to transplantation to keep patients alive during the waiting ...

Effects of Synchronized Cardiac Assist Device on Cardiac Energetics

Annals of the New York Academy of Sciences, 2006
Abstract:  A novel physiological cardiac assist device (PCAD), the LEV RAM assist device, which is synchronized with the failing heart ejection, was developed to improve the failing heart systolic and diastolic functions and cardiac energetics. The PCAD uses a single short cannula, which is inserted into the beating left ventricle (LV) by means of a ...

Cardiac Assist Devices

2010
Heart failure is the inability of the heart to pump blood at a rate ­commensurate with the requirements of the metabolizing tissues. This growing population of patients with refractory end-stage heart failure has been a major catalyst for the development of devices that assist or even replace the failing heart.

Cardiac Assist Devices

1992
The ultimate objective of any program developing a ventricle pump is to join two artificial ventricles together to form a total artificial heart. However, an initial objective has been to develop an assist pump, or ventricular assist device, for weaning a patient whose heart will not spontaneously beat after open heart surgery, by artificially assuming

The Present and Future of Cardiac Assist Devices

Artificial Organs, 1985
Abstract: This article describes the status of development of an implantable electrically powered ventricular assist device designed for a minimum of a 2‐year operation in patients with advanced heart failure. While these devices are envisioned for chronic support of the failing circulation, air‐driven blood pumps have been used to provide life ...

Current Advances in Cardiac Assist Devices [PDF]

open access: possible, 1992
Under the heading of circulatory assist devices, we include systems designed for complete or partial cardiac replacement. We exclude agents acting on myocardial contraction and peripheral circulation as well as so-called counter-pulsation procedures using intra-aortic balloons which modify pressure rather than the flow rate.

Temporary assist device for postcardiotomy cardiac failure

The Annals of Thoracic Surgery, 2004
Postcardiotomy left ventricular failure (LVF) complicating a cardiac surgical procedure is usually managed with intraaortic balloon pump (IABP) counterpulsation. We report two cases of postcardiotomy LVF unresponsive to inotropic support and IABP counterpulsation that were managed successfully with the use of the TandemHeart percutaneous ventricular ...

Biological Cardiac Assist Devices

2016
In this chapter, we present an overview of the field of biological pumps as they relate to heart failure. The concept of biological pumps is relatively new; therefore, we start with an overview of the field and describe the concept of biological pumps and the potential utilization of these devices to support infarcted hearts.

Simulation study of the Hemopump as a cardiac assist device

Medical & Biological Engineering & Computing, 2002
A dynamic model was developed for a Hemopump that withdraws blood from the left ventricle and discharges it to the aorta through a miniature axial-flow pump. Incorporation of the Hemopump model in a previously established model for the canine circulatory system enabled the effects of the Hemopump on various haemodynamic variables of the circulatory ...
