Cardiac Surgery
Perform cardiac imaging, measure blood flow and receive immediate feedback on how well a graft is functioning.
Intraoperative surgical guidance and quality assessment with ultrasonic imaging and blood flow measurement reduces risk of stroke for the patient. It also provides the surgeon with a tool to verify graft functionality, revise when needed and optimize the graft strategy during surgery.
These benefits are displayed in the first study to combine TTFM and High Frequency Ultrasound Imaging - the REQUEST Study.

Combining epicardial ultrasound imaging and TTFM enables the surgeon to perform a prompt and accurate revision of the graft.
Technical imperfections of an anastomosis can be immediately corrected in the operating room. Read more about the REQUEST study here.
Epiaortic imaging provides a sensitive and direct diagnosis of aortic disease. Evaluation of the ascending aorta prior to any manipulation may lead to modifications of the surgical strategy and thus contribute towards reduced rates of major adverse cardiac and cerebrovascular events (MACCE).
