A testing apparatus for a prosthetic valve, the testing apparatus comprising: a flow channel having a first end portion and a second end portion, and configured to hold a test fluid; a retainer configured to hold the prosthetic valve within the flow channel; a first fluid driver coupled to the first end portion of the flow channel and configured to move to flow the test fluid through the prosthetic valve in an outflow direction of the prosthetic valve, and configured to provide a pressure of the test fluid on an inflow side of the prosthetic valve; a second fluid driver coupled to the second end portion of the flow channel and configured to move to flow the test fluid through the prosthetic valve in the outflow direction of the prosthetic valve, and configured to provide a pressure of the test fluid on an outflow side of the prosthetic valve; and a controller configured to: move the first fluid driver and the second fluid driver to flow the test fluid through the prosthetic valve in the outflow direction of the prosthetic valve when the prosthetic valve is in an open state, operate the first fluid driver to provide a pressure profile of the test fluid on the inflow side of the prosthetic valve when the prosthetic valve is in a closed state, and operate the second fluid driver to provide a pressure profile of the test fluid on the outflow side of the prosthetic valve when the prosthetic valve is in the closed state. a flow channel having a first end portion and a second end portion, and configured to hold a test fluid; a retainer configured to hold the prosthetic valve within the flow channel; a first fluid driver coupled to the first end portion of the flow channel and configured to move to flow the test fluid through the prosthetic valve in an outflow direction of the prosthetic valve, and configured to provide a pressure of the test fluid on an inflow side of the prosthetic valve; a second fluid driver coupled to the second end portion of the flow channel and configured to move to flow the test fluid through the prosthetic valve in the outflow direction of the prosthetic valve, and configured to provide a pressure of the test fluid on an outflow side of the prosthetic valve; and a controller configured to: move the first fluid driver and the second fluid driver to flow the test fluid through the prosthetic valve in the outflow direction of the prosthetic valve when the prosthetic valve is in an open state, operate the first fluid driver to provide a pressure profile of the test fluid on the inflow side of the prosthetic valve when the prosthetic valve is in a closed state, and operate the second fluid driver to provide a pressure profile of the test fluid on the outflow side of the prosthetic valve when the prosthetic valve is in the closed state. move the first fluid driver and the second fluid driver to flow the test fluid through the prosthetic valve in the outflow direction of the prosthetic valve when the prosthetic valve is in an open state, operate the first fluid driver to provide a pressure profile of the test fluid on the inflow side of the prosthetic valve when the prosthetic valve is in a closed state, and operate the second fluid driver to provide a pressure profile of the test fluid on the outflow side of the prosthetic valve when the prosthetic valve is in the closed state.
