Intraoperative surgical guidance and quality assessment with ultrasonic imaging and blood flow measurement during cardiac surgery, reduce risk of stroke for the patient and provide the surgeon with a tool for verifying 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.

Epicardial ultrasound imaging provides important information about coronary artery stenosis; site, degree and shape of the coronary lesion.

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.

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).
