Although the experimental results of the total artificial heart implantation have rapidly improved and several calves have been reported recently as surviving longer than 100days, the respiratory failure after the implantation surgery is still one of the major problem for the cause of death. If the pumping work of the right side heart is much stronger than that of the left side heart, respiratory failure will happen.
Cardiac function curve of both side heart should be checked before the implantation by mock circulation. The relationship between right and left atrial pressure of the TAH implanted calves has been studied in this report.
