The CARMAT total artificial heart [PDF]
European Journal of Cardio-Thoracic Surgery, 2014 Research into the subject of total artificial heart (TAH) began in the USA in 1963 under the impetus of the American Congress; however, it soon hit the snags of haemocompatibility, autoadjustment of operation to the patient’s physiological needs, miniaturization, portable energy and reliability in the long run.

Four Artificial Heart Valves [PDF]
New England Journal of Medicine, 2005 A 67-year-old woman reported having progressive shortness of breath over several months, three years after undergoing aortic-valve replacement for aortic insufficiency. The patient had migraine headaches for which she had received 2 mg of ergotamine tartrate daily for many years. On physical examination, her blood pressure was 170/95 mm Hg.

Artificial heart transplants [PDF]
British Medical Bulletin, 1997 The use of a mechanical device to support a failing heart is one of the greatest challenges in cardiothoracic practice. Many different approaches are being considered, but they share the use of many advanced engineering principles. Power supplies and the interface between artificial surfaces and the blood remain areas of difficulty.

The need for artificial hearts. [PDF]
Heart, 1996 Chronic immunosuppression, allograft coronary disease, and restricted availability of donor organs continue to limit the scope of cardiac transplantation. Meanwhile increasingly favourable experience with implantable blood pumps used as a bridge to transplant has reintroduced the concept of permanent mechanical cardiac support.

A Nonpulsatile Artificial Heart
The Journal of ExtraCorporeal Technology, 1973 The concept of a nonpulsatile artificial heart is discussed. The approach used in this investigation embodies the principle of a constrained force vortex to propel the blood. This novel approach eliminates the need for the direct contact of blood with impellers and also alleviates the constrictive and mechanical forces on blood cells resulting from ...

Journal of thoracic disease, 2015 The total artificial heart (TAH) is a form of mechanical circulatory support in which the patient's native ventricles and valves are explanted and replaced by a pneumatically powered artificial heart. Currently, the TAH is approved for use in end-stage biventricular heart failure as a bridge to heart transplantation.
