A test bench assembly () for the simulation of cardiac surgery and/or interventional cardiology operations and/or procedures, comprising a passive heart (), wherein said passive heart () is an explanted or artificial or hybrid heart, said passive heart () having at least one pair of cardiac chambers () comprising an atrial chamber () and a ventricular chamber (); a reservoir (), adapted to house the working fluid; a pressure generator (), adapted to provide said passive heart () pumping said working fluid with the pumping function, said pressure generator () being fluidically connected both to said ventricular chamber () of said passive heart () and to said reservoir () by means of first fluid connection means; a pressure regulation device () which provides the working fluid in input to the atrial chamber () with the preload pressure, and the working fluid in output from the ventricular chamber () with the afterload pressure, said pressure regulation device () being fluidically connected both to said atrial chamber () of said passive heart () and to said ventricular chamber () of said passive heart () by means of second fluid connection means; wherein said pressure regulation device () comprises a single compliant element () for each pair of cardiac chambers () which provides the working fluid with both the preload and the afterload pressures.

Test bench assembly for the simulation of cardiac surgery and/or interventional cardiology operations and/or procedures

A test bench assembly for simulating cardiac surgery includes a passive heart having at least one pair of cardiac chambers with an atrial chamber and a ventricular chamber. A reservoir is adapted to house working fluid. A pressure generator fluidically connects both to the ventricular chamber of the passive heart and to the reservoir. A pressure regulation device provides working fluid in input to the atrial chamber with preload pressure, and working fluid in output from the ventricular chamber with afterload pressure. The pressure regulation device fluidically connects both to the atrial chamber of the passive heart and to the ventricular chamber of the passive heart. The pressure regulation device has a single compliant element for each pair of cardiac chambers, which provides working fluid with both preload, and afterload pressures.
