About

Valve PPM

This tool assists medical professionals in assessing implanted prosthetic cardiac valves. It offers guidance for checking existing valve function and selecting the optimal valve before implantation based on patient and prosthesis parameters.

Highlights
  • Assess implanted valve function
  • Select optimal valve before implantation
  • Analyze patient and prosthesis parameters
  • Identify potential patient-prosthesis mismatch
  • Determine intrinsic prosthesis dysfunction

Valve PPM is an innovative mobile tool developed to support echocardiography professionals in their effort of assessing the functionality of implanted prosthetic cardiac valves. The application provides guidelines for assessing an already implanted valve (Check Valve Function) and for choosing a valve before implantation (Optimal Valve Selector). 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 Valve Function 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), Valve PPM 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 Valve Selector The user will be required to select a valve position (aortic/mitral) and the patient characteristics (weight/height) and Valve PPM will instantly indicate the minimum Effective Orifice Area (EOA) in order to avoid Patient Prosthesis Mismatch (PPM).
