Fig. 4: Test results of the Hybrid Heart in vivo experiment in an acute goat experiment.

All data corresponds to the period during which the Hybrid Heart was providing all the blood flow in the animal, without additional support of the cardiopulmonary bypass. Data are presented as mean ± SD of n = 20 cycles with shaded error bars. a Systemic pressures measured during the in vivo experiment. AOP: aortic pressure, LVP: intra ventricular pressure of the left ventricle, LAP: left atrial pressure. b Aortic flow during the animal experiment. c Pressures of the pulmonary circulation measured during the animal experiment. PAP: pulmonary artery pressure, RVP: intra ventricular pressure of the right ventricle, RAP: right atrial pressure. d Pulmonary flow during the acute goat experiment. e Screen capture of the monitor during the animal experiment. Red line shows the blood pressure measured in the iliac artery (100/46 mmHg, mean 58 mmHg). f) Photo of the Hybrid Heart implanted in the goat.
