Previously only cleared for use in the coronary and peripheral blood vessels, PressureWire Certus can now be used to assess pressure measurements across heart valves and into various chambers of the heart. It can also be used in the assessment of Fractional Flow Reserve (FFR). FFR expresses the maximum achievable blood flow in a coronary artery with abnormal stenosis as a fraction of maximum blood flow in the absence of a stenosis.
