 We are currently conducting investigation in the validation of CorCTA against FFR in intermediate coronary artery stenoses 40-70 see below under Preliminary Data. However, CorCTA has not been validated against invasive hemodynamic measurements of fractional flow reserve in patients with stenoses 70 by invasive X-ray angiography. We hypothesize that CorCTA-derived measurements are accurate in the diagnosis of hemodynamically significant coronary artery stenoses, using FFR as the reference standard in patients with coronary artery stenoses70.
