A new computer modeling program approved by the US Food and Drug Administration (FDA) will permit clinicians to noninvasively evaluate blood flow in the coronary arteries of patients with symptoms of coronary artery disease (http://1.usa.gov/1FsmVpq).
The HeartFlow FFR-CT software uses data obtained from a computed tomographic (CT) scan of the heart to generate a measurement of fractional flow reserve (FFR), or the ratio of maximum flow in the presence of a vessel narrowing to normal maximum flow.
