pediatric cardiac screening

Catch more kids before a cardiac crisis.

A low-cost digital chestpiece and AI-assisted workflow for pediatric visits, sports physicals, and school-based screening—designed to widen the net, then refer only the concerning cases to a real cardiologist.

What is happening now

  • Prototype chestpiece in build
  • Model training underway
  • First wedge: pediatric wide-net screening and cardiology referral
High-risk cardiac conditions can stay silent until stress, exertion, or collapse.
why it matters
HCM

HCM is a leading sudden-death concern in young athletes—and many affected kids have few or no symptoms before an event.

triage challenge
2/3+

Over two-thirds of school-age children may have an innocent murmur, so frontline referral decisions are noisy.

market signal
AEDs

Schools are investing in cardiac emergency readiness. Ausculta is the upstream detection layer.

the gap

Pediatric cardiac risk hides inside routine care.

The issue is not that every child needs a cardiologist. The issue is that too many high-risk kids never generate enough signal to get referred in time—while most kids with murmurs are ultimately fine.

What slips through the cracks

Most screening still starts with a brief family-history review and a quick listen during well visits or sports physicals. That works for many kids, but it leaves a gray zone: the subtle murmur, the borderline concern, the repeat visit that never happens, the school athlete who looked healthy until the day they did not.

Ausculta framing
Not universal echo. Not fear-based over-referral.
Ausculta is a low-cost wide-net screen that helps pediatricians, schools, and sports programs capture better first-line data and route only the concerning cases to cardiology.
product

Ausculta adds structured audio at the point of first listen.

Think of it as a shared, low-cost screening workflow—not a premium gadget and not a replacement for cardiology.

1

Guided recording

A nurse, pediatrician, or school clinician records 10–15 second clips at 2–4 listening positions.

2

Quality check

The app checks signal quality before any interpretation so messy recordings do not masquerade as pathology.

3

Simple output

The output is intentionally narrow: repeat, watch, or refer.

4

Referral packet

Concerning cases generate a compact packet for pediatric cardiology review instead of a vague 'come back if it gets worse.'

Ausculta does not diagnose HCM on its own.

It helps catch the "I want one more datapoint before I decide" cases, then routes the real edge cases to a cardiologist faster.

screen wide → refer narrow
prototype

Prototype chestpiece design: simple, rugged, cheap enough to share.

The goal is not a luxury digital stethoscope. The goal is a small signal-capture tool that works with ordinary Android hardware.

Single-sided pediatric diaphragm
Low profile for fast placement on smaller chests.
BLE • USB-C • one button
Acoustic chamber + diaphragm

Single-sided chestpiece keeps the build cheaper, smaller, and easier to disinfect.

Commodity MEMS / electret mic

Enough fidelity for phonocardiogram capture without premium metal acoustics.

ESP32-class BLE microcontroller

On-device buffering, Bluetooth link, simple button control, and low power draw.

Small Li-ion cell + charge board

Recharge once and share across a clinic day, sports physical line, or screening event.

Optional 3.5 mm monitor path

Useful in noisy environments, training, or quick listen-back without cloud dependency.

Design principle: borrow the right parts from tele-auscultation and low-cost hardware literature, then optimize for pediatric workflow, signal quality, and shared-device reliability.
access

Designed for mass access, not premium-device margins.

These are target economics for a shared screening model and should be read as design goals, not final quotes.

today's premium category
$499

Current digital stethoscopes commonly retail around this benchmark.

Ausculta design target
$22–$35

Pilot BOM target using commodity electronics and existing Android hardware.

district / school model
<$1

Per-student aspiration when a shared device screens a few hundred children per year.

Shared screening kit = chestpiece + app + case. The goal is a service workflow, not a device for every exam room.
go to market

Start where the child already is.

The first buyers are not cardiology departments. They are the people already doing physicals, screenings, and referrals.

1

Pediatric groups

Well visits, school forms, sports clearance, repeat listens.

Fits naturally into routine care where most borderline cardiac questions already surface.

2

Schools + athletic programs

Mass participation sports physicals and event-day screening.

Creates an upstream detection layer before the emergency-response layer ever has to be used.

3

Children's hospitals + foundations

Community outreach, grant-funded screening days, referral partnerships.

Useful where mission, visibility, and pediatric cardiology access can reinforce each other.

mission

Build a commercial wedge that funds a humanitarian one.

The same low-cost screening stack can also support pediatric and rheumatic-heart-disease programs in lower-resource settings.

U.S. pediatric + school screenings

Shared-device programs generate revenue, operational data, and product feedback.

Lower-cost product iteration

Volume manufacturing and workflow simplification push screening cost down.

LMIC deployments + partners

Support children and adolescents in settings where pediatric cardiology access is thin.

A portion of profits can fund sponsored referral review, transport support, or treatment support for children identified through lower-resource screening partnerships.
