[Comment] A novel total artificial heart: search for haemocompatibility

During the past four decades several groups in the USA and Europe have developed and clinically implemented different cardiac prostheses or total artificial hearts (TAH)—the Cooley/Liotta TAH, Jarvik7 TAH, Bücherl Heart TAH, AbioCor TAH, and CardioWest TAH (TAH-t), which is currently in use. The aim of TAHs is to mimic native heart anatomy and function, fitting into the pericardial cavity and providing pulsatile unidirectional blood flow from the atria to the great arteries in patients with end-stage biventricular heart failure.
