9 Promising Cardio Technologies: Noninvasive Assessment of Coronary Artery Blockages

Noninvasive Assessment of Coronary Artery Blockages

Noninvasive Assessment of Coronary Artery Blockages

A sample simulated heart model from HeartFlow pinpoints a red artery as having a problematic FFRCT estimate of 0.58.

To avoid over-stenting, physicians can determine whether a coronary artery needs to be stented by using fractional flow reserve (FFR) technology. But FFR requires cardiac catheterization.

That's where the latest advancement, called FFRCT, comes in. The innovation, from HeartFlow Inc., uses information from a CT scan to approximate an FFR measurement. The CT scan is used to simulate blood flow through a 3-D computer model of the heart. The physician receives a report with a color-coded print out of the heart, with different colors corresponding to different FFRCT values.

The FFRCT received de novo clearance from FDA in late 2014. According to the FDA press release, FFRCT has been shown to match FFR for 84% of artery blockages that would need treatment and 86% that would not need treatment.
