## What is Echo Quant?

Stop scribbling continuity equations on scrap paper. Echo Quant turns raw TTE measurements into graded, report-ready numbers — in seconds, fully offline.

Built for medical students, residents, cardiology fellows, and cardiac sonographers learning echo quantification.

EIGHT GUIDED MODULES
• Aortic Stenosis — continuity-equation AVA, indexed AVA, DVI, gradients
• Aortic Regurgitation — PISA, EROA, regurgitant volume, vena contracta
• Mitral Stenosis — pressure half-time and deceleration-time MVA
• Mitral Regurgitation — PISA quantification with integrated grading
• Pressures — RVSP/PASP, PAEDP, mPAP, PVR, estimated LAP
• Chambers — sex-specific normal ranges with report-ready output
• Tricuspid & Pulmonic — stenosis and regurgitation quantification
• Diastolic Function — the ASE grading algorithm, variable by variable

WHY TRAINEES KEEP IT ON THE HOME SCREEN
• Severity meters grade every value live against published ASE-style thresholds
• Every module shows its formula — learn the math while you use it
• One-tap, copy-ready report lines for practice reads
• Fully referenced: every formula cites its published ASE/EACVI guideline source, with links

PRIVATE BY DESIGN
Works completely offline. No account. No ads. No analytics. No data collection — everything stays on your device.

IMPORTANT
Echo Quant is an educational reference only. It is not a medical device and is not intended for diagnosis, treatment, or any clinical decision-making. Always verify values independently and follow current society guidelines and institutional protocols.

## Key features

- Offline TTE measurement calculation
