A study published in the Journal of the American Society of Echocardiography (JASE) has confirmed the ability of EchoNous’ Kosmos to accurately measure peak aortic valve jet velocity and help physicians assess aortic stenosis (AS) severity.
Kosmos is the only handheld echocardiography device that features both Continuous-Wave (CW) and Pulsed Wave (PW) Doppler capabilities. In addition, Kosmos offers full-resolution scanning and has been benchmarked against high-end, cart-based reference point-of-care ultrasound (POCUS) systems.
Additionally, the study compared Kosmos’ aortic stenosis severity classifications with those made by an independent experienced observer. This comparative evaluation tested the Kosmos platform’s ability to differentiate patients with mild aortic stenosis - or none at all - and those suffering from moderate-to-advanced AS. Results showed that reliable classification was possible with Kosmos in 94% of patients with visually mild stenosis. These findings are important because most devices in the handheld POCUS market do not have CW Doppler, and therefore make it more challenging to diagnose patients with visually mild aortic stenosis.
“EchoNous set out to build an AI automated ‘power tool’ that can handle the heavy lifting of diagnostic challenges - those faced by Cardiology critical care and all other POCUS users,” explained Kevin Goodwin, CEO of EchoNous. “The AI automation on Kosmos is showing true promise, validated by studies soon to be published showing that it reduces learning and competence cycle time for novice users.”

About the Study
Titled “A Novel Handheld Echocardiography Device with Continuous-Wave Doppler Capability: Implications for the Evaluation of Aortic Stenosis Severity,” The study published by JASE recorded results from 118 consecutive patients with known or suspected aortic stenosis as they were scanned with Kosmos, as well as a high-end echocardiography system using continuous wave Doppler.Findings
When results were compared, Kosmos was found to reliably measure peak aortic jet velocity. The Kosmos device accurately detected at least moderate aortic stenosis with 93% sensitivity, 98% specificity, positive predictive value (PPV) of 98%; negative predictive value (NPV) of 94%, and a total accuracy of 96%. Additionally, the study showed that Kosmos reliably identified clinically significant aortic stenosis and facilitated aortic stenosis grading when used by experienced operators.Additionally, the study compared Kosmos’ aortic stenosis severity classifications with those made by an independent experienced observer.
