Research published in Heart and Lung Circulation has revealed CAAS vFFR (vessel Fractional-Flow-Reserve) is on the way to becoming a reliable clinical tool for clinicians. vFFR calculates the pressure drop in coronary vessels without the need for a pressure wire or hyperemic agent like traditional FFR. CAAS vFFR software uses two angiograms to build a 3D reconstruction of the vessel which can be analyzed.
The blinded study revealed that vFFR use results in a significant reduction in analysis time to allow for more rapid decision making. With vFFR taking 2.37mins compared to 17.45 mins for traditional FFR. That’s 15 mins of time saving per procedure.
Traditional FFR is currently the gold standard technique for guiding decision making for coronary revascularization. However, it has had limited uptake due to real-world challenges such as high variability, unreliability and workflow implementation challenges. Caas vFFR aims to offer a less invasive, safer, faster and less costly way to assess the same patients.
