Circle Cardiovascular Imaging vs Ultromics EchoGo
A cardiology department that runs cardiac MR and CT analysis next to an echo lab can buy both of these. The cvi42 platform lists modules for cardiac MR, cardiac CT, AI plaque analysis, vascular CT, interventional planning and electrophysiology, and StrokeSENS covers acute stroke CT and CTA. EchoGo works on transthoracic echocardiography.
The regulatory records differ in size. openFDA lists twelve decisions under the applicant names Circle Cardiovascular Imaging and Circle Neurovascular Imaging, including K251027 for the cvi42 Coronary Plaque Software Application on October 27, 2025. For Ultromics, the vendor says EchoGo Heart Failure showed 90.3% sensitivity and 86.1% specificity in clinical evaluation, citing K240013.
For a department building a coronary plaque program on CT, Ultromics sits on the wrong modality, since EchoGo reads echocardiography and not CT or MR. A department whose first goal is an HFpEF flag on routine echo studies starts with EchoGo.
