EchoGuide by ASE vs CathPal

ASE’s EchoGuide provides access to over 50 calculators, algorithms, and charts. EchoGuide was developed based on key ASE guidelines for use by healthcare professionals providing cardiac care. One special feature in the app is that users have the ability to select their favorite interactive tools for easy access. Topics include: • Left Ventricle • Left Ventricle Mass • Left Ventricular Diastolic Function • Right Ventricle • Left Atrium • Right Atrium Dimensions & Volumes • Aorta • Aortic Regurgitation • Aortic Stenosis • Mitral Regurgitation • Mitral Stenosis • Tricuspid Regurgitation • Tricuspid Stenosis • Pulmonic Regurgitation • Pulmonic Stenosis • Prosthetic Aortic Valve Function • Prosthetic Mitral Valve Function • Prosthetic Tricuspid Valve Function • Prosthetic Pulmonic Valve Function • Prosthetic Valve Regurgitation EchoGuide is intended for educational/informational use only. EchoGuide is not intended for use in the diagnosis of disease or other conditions, or in the cure, mitigation, treatment, or prevention of disease by aiding clinical decision-making. Please send feedback through the App information page and feel free to leave a review and rating in the App Store.

CathPal is a comprehensive hemodynamic calculator for cardiac catheterization. Built by a cardiologist, for cardiologists. IMPORTANT — MEDICAL DISCLAIMER CathPal is an educational and decision-support tool intended for use by licensed healthcare professionals trained in cardiac hemodynamics. It is not a medical device. It does not diagnose disease, prescribe treatment, or replace clinical judgment. All calculated values must be interpreted in the context of the individual patient by a qualified physician. No clinical decision should be made based on the output of this app alone. If you are not a healthcare professional, do not use this app to make decisions about your own health or the health of another person. Always consult a qualified physician in addition to using this app and before making any medical decision. Never disregard professional medical advice or delay seeking it because of information obtained from this app. In an emergency, call your local emergency number immediately. All formulas, reference ranges, and thresholds in CathPal are drawn from peer-reviewed literature and professional society guidelines. Full citations — including the 2022 ESC/ERS Pulmonary Hypertension Guidelines, the 2020 ACC/AHA Valvular Heart Disease Guideline, and the original Gorlin, Hakki, LaFarge, Flamm, PAPi (Korabathina), CPO (Fincke), ARI (Sinning), and SCAI cardiogenic shock publications — are listed inside the app under "Disclaimer & References" and alongside each formula in the Equations view. Enter your catheterization data and instantly compute Fick and thermodilution cardiac output, pulmonary and systemic vascular resistance, RV performance indices, Gorlin and Hakki valve areas, and complete shunt quantification — all with an EMR-ready evaluation report you can copy and paste directly into the chart. HEMODYNAMIC CALCULATIONS • Fick cardiac output with LaFarge VO₂ estimation • Thermodilution CO with multi-run averaging • PVR, SVR, PVRI, SVRI (Wood units and dyn·s·cm⁻⁵) • PAPi, RVSWI, CPO, CPI — shock and RV performance indices • Pulmonary hypertension classification (2022 ESC/ERS criteria) • Cardiac index, stroke volume, stroke volume index VALVE AREAS • Gorlin equation for aortic (AVA) and mitral (MVA) valve areas • Hakki simplified formula (CO/√gradient) • AFib mode with per-beat averaging (up to 10 beats) • Automatic SEP and DFP calculation from ejection/filling times SHUNT QUANTIFICATION • Full oximetry run with step-up detection and localization • Qp/Qs ratio with absolute flow calculations • Shunt-adjusted PVR and SVR • Eisenmenger physiology warning SMART FEATURES • Auto-tab between pressure fields for rapid data entry • Quality checks flag impossible values and common entry errors • Algorithmic interpretation based on published guidelines • EMR-ready evaluation report with plain text (EHR) toggle • Dark mode support WORKS OFFLINE No account required.
