The CathWorks FFRangio®* System is a software device for the clinical quantitative and qualitative analysis of previously acquired angiography DICOM data for patients with coronary artery disease. It provides FFRangio, a mathematically derived quantity, computed from simulated blood flow information obtained from a 3D computer model, generated from coronary angiography images. FFRangio analysis is intended to support the functional evaluation of coronary artery disease. The results of this analysis are provided as a supportive aid for qualified clinicians in the evaluation and assessment of coronary artery physiology. The results of CathWorks FFRangio are intended to be used by qualified clinicians in conjunction with the patient’s clinical history, symptoms, and other diagnostic tests, as well as the clinician’s professional evaluation.
There are no known contraindications for use of FFRangio.
The safety and effectiveness of the FFRangio has not been established in pediatric patients.
FFRangio results may be adversely affected by the following:
Quantitative lumen diameter and QCA measurements are representative of the geometric model and the accuracy is dependent on the quality of the angiography data provided.
Due to the possible variability in the FFRangio results, the results should be viewed as one of several clinical data points in addition to the patient’s angiographic images, clinical history, symptoms, other diagnostic tests, and an appropriately trained clinician’s clinical judgment to evaluate the patient.
The effectiveness of FFRangio has not been evaluated for the following populations:
CAUTION: Federal (USA) law restricts this device to sale by or on the order of a physician.
