Accurate assessment of coronary blood flow by continuous thermodilution technique: Validation in a swine model

To assess the accuracy of coronary thermodilution measurements made with the RayFlow® infusion catheter.Measurements of absolute coronary blood flow (ABF) and absolute microvascular resistance (Rμ ) by continuous coronary thermodilution can be obtained in humans but their accuracy using a novel dedicated infusion catheter has not yet been validated. We compared ABF values obtained at different infusion rates to coronary blood flow (CBF) values...
