Premarket evidence — what FDA accepted
source quote (p.4)
“AutoAS is a software application intended to assist medical professionals in the assessment of moderate/severe aortic stenosis (AS).”
source quote (p.14)
“Both devices utilize deep-learning artificial intelligence as the core technology to provide diagnostic aid to the user in the assessment of heart conditions.”

“Software documentation generated as part of the design process included: ... Cybersecurity”
Validation studies (2)
Standalone
n=401 patients · 4 site(s)
endpoints: Area Under the ROC Curve; Specificity; Sensitivity
Reader study (MRMC)
n=220 patients · 3 site(s)
endpoints: sensitivity; specificity; partial AUROC; inter-rater agreement
Reported performance (6 observations)
source quote (p.9)
“Specificity of 92.4% [95% CI: 86.3% - 98.4%] and sensitivity of 75.2% [95% CI: 67.4% - 83.0%] were observed, on par with original reading cardiologists when compared to the same reference panel).”

“Specificity of 92.4% [95% CI: 86.3% - 98.4%] and sensitivity of 75.2% [95% CI: 67.4% - 83.0%] were observed, on par with original reading cardiologists when compared to the same reference panel).”
source quote (p.9)
“The standalone assessment findings demonstrated strong overall performance; Area Under the ROC Curve, 93.2% [95% CI: 90.5% - 95.6%] which is statistically significantly greater than the predefined performance target.”
source quote (p.11)
“A statistically significant improvement in sensitivity was observed for the “Aided” readers compared to the “Unaided” readers (+ 5.5%, 95% CI: (1.5%, 9.5%))”
source quote (p.11)
“the critical region of the ROC curve revealed superiority for the “Aided” group with an 8.9% [95% CI: 1.2%, 20.5%] difference in partial AUROC.”
source quote (p.11)
“In addition, aided readers demonstrated higher inter-rater agreement (89.0%) than unaided readers (81.9%), comparable to the reference standard (88.7%), reflecting improved reader consistency and diagnostic performance.”

Postmarket — what happened after clearance
Recall and MAUDE counts are product-code-level (reports aren't reliably attributable to one device). Signals are descriptive observables with sources — never a judgment that the device is unsafe or drifting. Snapshot 2026-07-08.
Reimbursement — how devices like this got paid
Not yet tracked — no payment pathway indexed for this clearance (the reimbursement corpus is a growing seed set).
