Investigation of the Role of Hemodynamics in Re-stenosis of CABG Patients

The CTA is non-invasive and is used commonly for patients who have chest pain to assess the coronary artery disease, prior to the more invasive coronary angiogram.

This procedure involves the insertion of a Medistim Ultrasound Transit Time Flow Probe into the graft vessel to measure its flow rate. This technique is commonly used for evaluating graft opening during CABG surgery.
