Artrya

What does Artrya say Salix does?

According to the vendor, Artrya partners with clinics that receive chest pain patients, and its AI shows the type and volume of arterial plaque from CCTA so patients can be stratified "within minutes". The vendor describes detection of the location and extent of atherosclerosis and plaque features such as low attenuation plaque, a personalized 3D heart model, and standardized reports with plaque volume and composition aligned to SCCT guidelines. It adds that two convolutional neural network models extract centerlines, trained on "thousands of scans" from the US, Australia and Canada.

Which Salix modules are cleared, and where?

The site names Salix Coronary Anatomy, Salix Central and Salix Coronary Plaque. FDA lists Salix Central as K243038, cleared March 27, 2025, and Salix Coronary Plaque (V1.0.0) as K251837, cleared August 20, 2025. Salix Coronary Anatomy is on the Australian register as ARTG 347719.

The vendor's indications page defines Salix as software for trained medical professionals who analyze cardiac CT data for coronary plaque and stenosis and for calcium scoring in patients who had CCTA to evaluate coronary artery disease, and it states that Salix is an adjunct and does not replace a health professional's own review.

What evidence does the vendor give?

Two epidemiology citations carry the rationale on the site. Williams 2020 is quoted for 42% of heart attack victims having less than 50% stenosis, and Villines and Williams 2022 for 18% of patients with a zero calcium score having problematic, highly progressive low attenuation plaque. Neither citation tests Salix. A PubMed search on Artrya and the Salix module names returned no papers about the product.

Who sells Salix, and how?

Salix is sold through a "Request A Demo" page on the vendor's site, and no price is listed there. Founding year and funding are not verified.

The verdict

Salix suits a cardiac CT service that already runs CCTA and is prepared to rely on the FDA clearances and the vendor's own descriptions, since the evidence on the vendor's site is epidemiology. A service buying in Europe or the UK has only a contact route, because the site gives no CE or UKCA status.
