PrEssure wiRe Compared to Microcatheter-based Sensing Technology For the Evaluation of cORonary Fractional Flow Reserve Measurements
In Brief
A clinical study evaluating St. Jude Medical Pressure Wire and ACIST Navvus Microcatheter for Ischemia and Angina. Completed, enrolled 74 participants across 1 site.
Detailed Summary
The model by which physicians measure the lack of blood flow in the vessels that supply blood to the heart muscle is called Fractional Flow Reserve (FFR). FFR is the measurement of the pressure across the vessels that supply blood to the heart. These are known as the coronary arteries. This study involves comparing two FFR wires, the St. Jude Medical Pressure Wire (PW) and the ACIST Navvus Microcatheter (MC) to check the accuracy of the devices. FFR allows real-time estimation of the effects of a narrowed vessel, whereas standard angiography can underestimate or overestimate narrowing, because it only visualizes contrast (the different areas of color) inside a vessel.

Interventions
FFR measurement will be obtained with a PW with the FFR measurement obtained by using a MC within the same subject across the same target lesion at the same time
