Abstract

Approximately 5.7 million people in the United States have a diagnosis of heart failure, and more than 3,100 patients are awaiting a heart transplant. A temporary total artificial heart (TAH-t, SynCardia Systems Inc, Tucson, Arizona) is approved by the US Food and Drug Administration (FDA) as a bridge to transplant in patients at risk of dying of biventricular heart failure. Currently, TAH-t recipients awaiting transplant are hospital-bound and attached to a large pneumatic driver. In 2010, the FDA gave conditional approval for an Investigational Device Exemption clinical study of the portable Freedom driver (SynCardia). This case report describes a 61-year-old man admitted with acute decompensated heart failure, which progressively worsened, eventually requiring implantation of a TAH-t. Following stabilization, the patient was switched to the Freedom driver. After the patient and his wife proved competence in managing the device, they were able to take several daylong excursions outside the hospital. The patient considered discharge from the hospital while awaiting a transplant but ultimately received a heart transplant while still an inpatient. Higher rates of survival to transplant have already been proved with the TAH-t. Po...Continue Reading

Cardiomyopathy

Cardiomyopathy is a disease of the heart muscle, that can lead to muscular or electrical dysfunction of the heart. It is often an irreversible disease that is associated with a poor prognosis. There are different causes and classifications of cardiomyopathies. Here are the latest discoveries pertaining to this disease.

Artificial Heart & Ventricular Assist Devices

Total artificial hearts (TAH) and ventricular assist devices (VADs) provide cardiac support for patients with end-stage heart disease and have significantly improved the survival of these patients. Discover the latest research on Artificial Heart and Ventricular Assist Devices here.
