## What is Echodex?

The TTE values you look up every day — graded, color-coded, and cited — one tap away. Built by a cardiologist for the reading room.

WHO IT'S FOR
Cardiologists, cardiology fellows, sonographers, and any clinician who performs or interprets transthoracic echocardiograms — at the scanner, in the reading room, or on rounds.

FIND IT FAST
Six color-coded sections — Chambers, Stenosis, Regurgitation, Diastology, Pericardium, Formulas — one tap from the top of every screen. Severity ramps make mild vs moderate vs severe legible at a glance. Star the cards you use most and they pin to the top.

COMPLETE COVERAGE
• Chambers: LV size and function, LV mass, RV, atria, aortic root, IVC → RA pressure
• Stenosis: aortic, mitral, tricuspid, pulmonic — velocities, gradients, valve areas
• Regurgitation: vena contracta, EROA, regurgitant volume and fraction for all four valves
• Diastology: the 2025 cut-points and the exceptions where they don't apply
• Pericardium: tamponade, constriction, constriction vs restriction, effusion grading
• Formulas: Bernoulli, continuity, PISA, volumetric, right- and left-sided pressures

BUILT FOR THE BEDSIDE
Works fully offline — no login, no ads, no data collection. Light and dark themes. Follows your system text size.

EVERY VALUE CITED
Every card carries superscript markers that jump to the full citation, straight from the ASE, EACVI, and ACC/AHA guidelines: chamber quantification (2015), aortic stenosis focused update (2017), valve stenosis (2009), valvular heart disease (2020), native valvular regurgitation (2017), diastolic function (2025), and pericardial disease (2013).

FOR CLINICIANS
For licensed clinicians and trainees. The app performs no calculations, stores no patient data, and makes no diagnosis; it is not a substitute for clinical judgement or the source guidelines.

## Key features

- Color-coded reference sections
- Severity ramps for quick assessment
