Cardio Valve is an innovative mobile tool developed to support echocardiography professionals in their effort of assesing the functionality of implanted prosthetic cardiac valves. The application provides guidelines for assesing an already implanted valve (Check Prosthesis) and for choosing a valve before implantation (Optimal Prosthesis). The algorithms behind the App have been derived after an extensive research of the published materials on the aortic and mitral prosthetic valve assessment. - Check Prosthesis After selecting a particular valve type, the patient characteristics (weight/height) and the prosthesis actual parameters (peak velocity, mean gradient, VTI prosthesis, VTI LVOT and LVOTd), Cardio Valve will provide the user with an answer regarding the normal function of the valve, the potential patient prosthesis mismatch or the intrinsic prosthesis dysfunction. - Optimal Prosthesis The user will be required to select a valve position (aortic/mitral) and the patient characteristics (weight/height) and Cardio Valve will instantly indicate the minimum Effective Orifice Area (EOA) in order to avoid Patient Prosthesis Mismatch (PPM).
