The Evidence
Built on real-world implementation,
not theory.
We have already built the foundation. Every critical component of VLOOP has been executed in the field — across the United States and Ghana.
We Have Already Built the Foundation
Two proving grounds, one workflow
United States
VLOOP Community Pilot
- 5 community cardiovascular evaluation events
- Older adult population with portable echocardiography
- AI-enabled workflow with successful cardiology referrals
Lessons learned
Community demand exists. Workflow is feasible. Detection alone is not enough — navigation is essential.

Scientific Foundation
Two landmark studies opened the door
HUDDLE and PREVUE-VALVE each answered a critical question — and each left one unanswered.
“Prevalence of Cardiovascular Disease and Risk Factors Among Former National Football League Players”
Okoh AK, et al. J Am Coll Cardiol. 2024;83(19).
What HUDDLE demonstrated
- Community cardiovascular evaluation is feasible
- Portable echocardiography successfully identifies structural heart disease
- Older adults actively engage with community-based programs
HUDDLE answered: Can we identify disease? Yes.
One critical question remained: What happens after identification?
“Population Prevalence of Valvular Heart Disease in the United States: The PREVUE-VALVE Study”
Brener MI, et al. J Am Coll Cardiol. 2026;87(23).
What PREVUE demonstrated
- Structural valve disease is far more common than recognized
- Prevalence increases substantially with age
- Significant numbers of older adults remain completely undiagnosed
PREVUE answered: How common is disease? More common than expected.
One critical question remained: How do we consistently connect these patients to specialty care?
The Missing Link
VLOOP completes the pathway
HUDDLE and PREVUE established that disease exists and can be found. VLOOP is the implementation bridge between diagnosis and treatment — the critical infrastructure that neither study was designed to build.
HUDDLE
Can we find disease?
PREVUE
How common is it?
VLOOP
Can we identify, triage and connect patients?
