Total Artificial Heart (TAH)

2 valves bilaterally with empty space below (air) and nice rim of air around heart with no cannulas going to aorta or pulmonary vessels signifies total artificial heart.

TAH works on the principal of "Full eject, Partial fill" which gives good 2 pockets of air below valves. TAH works via air pump with negative vacuum pressure and cannulas come out from TAH to machine, in contrast to assist devices where big vessels get cannulated.
