Heart failure is the inability of the heart to pump blood at a rate Âcommensurate 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.

Physiologic Control of Cardiac Assist Devices
Artificial Organs, 1996Abstract: Total artificial hearts (TAHs) and biventricular assist devices (BVADs) have varying levels of acceptance and reliability, and the research on both focuses on their control mechanisms. Efforts generally aim to achieve a response to physiologic demand and left/right output balance, and beneficial cardiac output (CO) and effective control ...

Cardiac transplantation and ventricular assist devices
Current Opinion in Cardiology, 1991During the last decade, heart transplantation has become an almost routine clinical entity limited only by the number of donors available. Temporary ventricular support has also gained acceptance for two particular groups of patients: 1) those in cardiogenic shock with reversible ventricular failure and 2) those with irreversible ventricular failure ...

Ventricular Assist Devices in Pediatric Cardiac Surgery
The Annals of Thoracic Surgery, 1995Early 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.

Effects of Synchronized Cardiac Assist Device on Cardiac Energetics
Annals of the New York Academy of Sciences, 2006Abstract:  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 ...

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

Biological Cardiac Assist Devices
2016In 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.

Echocardiography and cardiac assist devices.
Minerva cardioangiologica, 2007Mechanical circulatory support is, nowadays, a well established treatment modality for end stage heart failure. Patients candidate for cardiac transplantation who decompensate while awaiting graft can be supported by long-term left ventricular assist devices (long-term LVAD). These devices are intracorporeal pumps, expensive and complicated to install,
