The management for the circulatory systems after total artificial heart replacement is very simple. We are using Utah heart driver systems. Both sides of air drive-line pressure waveform should be monitored in all cases.
The driving parameters of the heart driver are ajusted to the optimum by watching the monitor ing these air-driving pressure waveform and we can perceive abnormal changes of the driving systems including inside the heart from these pressure waveforms.
Eight calves were replaced with total artifici al heart in our department and one calf surviv ed 15 days after surgery. Recently we are using Japanese artificial hearts which made in Tomasu Technical Company in Himeji. One calf with Tomasu Heart died on the 9th day after surgery due to air leakage from the ventricle and there was no thrombus formation inside the heart at necropsy.
