Abstract
Disclosed herein is a 3D printed heart model with simulated cardiac stroke volumes. It involves an inner membrane conforming to the shape of the inner lining of the ventricle. This results in the creation of a compression pouch with a potential space (compression sac) bordered by the inner surface of the simulated ventricle and the outer surface of the inner membrane. The inner membrane also defines a neo-ventricular chamber that is in contact with blood simulating fluid. A pulsatile flow pump can serve as a hydrodynamic driver for inflow and outflow into and out of the compression sac. This can exert a concentric force that compresses the inner sac and displaces the simulated blood residing in the neo ventricular cavity simulating systole. The fluid can then return back from the compression sac to the pump allowing the neo-ventricle to distend to accommodate returning simulated blood from the atrium simulating diastole.
