Current Limitations
The Challenge
Current Technologies Are Not Designed to Meet the Need
Echocardiogram
Most cases of aortic stenosis are caught after a patient shows symptoms and are referred to a cardiologist for an echocardiogram to confirm diagnosis.
This flow ignores the roughly 50% of patients that develop severe AS before showing symptoms.
An echocardiogram can cost as much as $5,000, making it too costly to use as a screening tool$5,000
Echocardiograms require expertise that further restricts their adoption to support screening for AS
Digital Stethoscopes
Digital stethoscopes could offer a cheaper alternative to early detection that require less expertise, but despite existing since the 1990s, they still are not widely adopted.
A 2025 study found that even the leading digital stethoscope company faced:
Inefficient Results:Triple the false positive rate compared to traditional auscultation*3x
High Adoption Costs:Requires extra device, headphones, and charged battery to function
Low Utilization:60% after 12 months in 2025 TRICORDER study*60%
Low Value Increase:Device designed for those with auscultation expertise
There is a need for a new low-cost screening tool with a better product-market fit that can reach symptomatic and asymptomatic AS patients
We are building a breakthrough diagnostic solution for early detection of aortic stenosis, enabling timely intervention and improved patient outcomes.
