Advances in Hemodynamic Analysis in Cardiovascular Diseases Investigation of Energetic Characteristics of Adult and Pediatric Sputnik Left Ventricular Assist Devices during Mock Circulation Support

Figure 3

(a) Hydrodynamic system simulator (right) coupled to the circulatory system simulation (left). The left ventricular pressure p1 (preload) and the aortic arch pressure p2 (afterload) are calculated via the simulation and used as reference values for the hybrid adult mock circulation. Measured values in the experimental setup are indicated by ellipsoids, modified from the literature values. (b) Photo of the hybrid adult mock circulation (HAMC). The preload and afterload pressure compartments with the attached voice coil actuators can be seen as well as the three gear pumps providing the flow balance in the system. The device under test is mounted in the fixation in front. A detailed description of the system can be found in [3].
