VC-backed Circle Cardiovascular Imaging acquires Corstem

Circle Cardiovascular Imaging Inc has acquired Corstem Inc, a Montréal-based machine learning and artificial intelligence software developer focused on cardiac imaging analysis. No financial terms were disclosed. Circle, a Calgary-based developer of advanced, post-processing solutions for the cardiac imaging industry, said the deal will expand its technology and offerings. Corstem's platform will be integrated into Circle's core product, cvi42, a cardiovascular imaging reading and reporting solution. Last year, Circle raised $16 million in a round led by Kayne Anderson Capital Advisors and Yaletown Partners.
