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

Read full description

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).

Echo Calculate is a clinical reference and calculation tool designed for echocardiography and cardiovascular assessment workflows. Quickly access structured calculators, reference ranges, patient measurement tracking, and trend-based follow-up tools in one place. KEY FEATURES Clinical Calculators Access organised calculation categories for: • Aortic, mitral, pulmonary and tricuspid valve assessment • Hemodynamics • Left ventricular function • Right ventricular function • Diastolic function • Body size calculations • Chamber size and indexing • Regurgitation assessment • Doppler utilities Patient Measurement Tracking Create local patient profiles and record dated cardiovascular measurements over time. Track values such as: • Aortic Valve Area (AVA) • Mitral Valve Area (MVA) • Pressure gradients • Body Surface Area (BSA) • Body Mass Index (BMI) • Doppler measurements • Chamber measurements • Additional echocardiographic parameters Follow-Up Overview Echo Calculate organises patient records into a clear follow-up overview, helping users review stored measurements and identify which records may require closer attention. Automatic Reports Generate structured summaries from saved measurements. Reports combine dated records, measurement values and trend information into an easy-to-read format. Clinical Reference Ranges Access organised cardiovascular reference ranges and supporting information directly inside the app. Fast Search Quickly find calculations and measurements using familiar abbreviations and terms such as AVA, EF, RVSP, PISA, E/e′ and more. Multi-Language Support Use the app in multiple supported languages through the built-in language selector. Designed for Practical Use Echo Calculate features a clean, structured interface designed for fast access during study, education and professional clinical workflows. IMPORTANT MEDICAL DISCLAIMER Echo Calculate is intended as a calculation, education and clinical reference support tool. It does not provide a medical diagnosis and does not replace professional clinical judgement, medical examination, official guidelines or advice from a qualified healthcare professional. All calculated results and generated reports must be independently reviewed and interpreted in the context of the complete clinical picture. For medical concerns or emergencies, contact a qualified healthcare professional or emergency service.
