Rayflow catheter-Exact position of the Rayflow catheter was taken into account to determine the amount of myocardial mass (figure 1) Because even in normal coronary arteries, the presence of the infusion catheter may influence the measured blood flow (creating a small gradient), the flow in the absence of a stenosis is determined by the Coroventis software (Qnorm) by dividing the actuallyThe main difference between FFR evaluation using the RayFlow catheter and dedicated pressure microcatheters to measure FFR is that the RayFlow catheter has

Recovery of absolute coronary flow and resistance one week after percutaneous coronary intervention of a chronic totally occluded coronary artery using the novel RayFlow© infusion catheter EuroIntervention 18;14e5e5 published online November 17 published online eedition August 18 In FFRnegative patients, after removal of the Wirecath®, the Abbott PressureWire® is used in LAD – first to measure CFR by saline bolus injections and thermodilution during rest and hyperemia (Bolusthermo CFR) and – second together with a Hexacath/Rayflow® infusion catheter and a saline infusion pump to measure absolute flow during rest and hyperemia that will be usedThe Rayflow catheter is shown in the upper panel, clearly indicating the 4 infusion holes at 0°, 90°, 180°, and 270° The middle panel shows the infusion pump The lower panel shows the pressure wire with the necessary software Like with every invasive imaging modality, there are some practical issues to keep in mind when using this technique First, the Rayflow catheter is
CARACTÉRISTIQUES DU RAYFLOW La coronarographie continue réalisée avec le cathéter RayFlow™ permet une évaluation quantitative directe de la fonction microvasculaire en mesurant le débit coronarien et les résistances microvasculaires Utilisée en combinaison avec un fil de température/pression, cette nouvelle technologie permet d'explorer de nouveaux horizons en3 User Guide RayFlow Client 60 RayFlow Client 60 60 Table of Contents Introduction 4 Over this wire, a RayFlow ® catheter is advanced in the proximal part of the artery, and saline at room temperature is infused at a rate of 15 to mL/min through the 4 lateral side holes of the catheter This infusion induces steadystate hyperemia after approximately 15 seconds The temperature of the distal part of the artery decreases and reaches a steady state approximately after 25 seconds Then, the sensor is pulled back in RayFlow
Introduction Absolute coronary blood flow and resistance can be measured by thermodilution with a dedicated catheter (RayFlow, HexaCath, Paris, France) Purpose The infusion of saline (15–25 mL/min) through the RayFlow Catheter induces maximal hyperaemia We aimed to explore the mechanisms of this hyperemic response Methods In 19 domestic swines, instrumented withSeoul, Korea, april 25th, 17 Nico H J Pijls, MD, PhD Catharina Hospital, Eindhoven, The Netherlands TCT Asia Pacific 17 FFR, iFR, Contrast FFR, CFR, IMR, etcRayFlow ist eine Workflow ManagementLösung, die nicht nur alle wichtigen Informationen eines Auftrages in jeder Phase beliebig komplexer Prozesse bedarfsgerecht sammelt und bereitstellt, sondern auch als Bindeglied zwischen Teams und deren eingesetzten Softwareprodukten fungiert RayFlow steuert und überwacht den Workflow für den gesamten Application Lifecycle, vom
