In clinical practice, a normal or near-normal invasive coronary angiogram is considered to be reliable evidence for the absence of hemodynamically significant coronary artery disease. We present 2 patients with near-normal coronary angiograms who had noninvasive evidence of vessel-specific ischemia confirmed by invasive measurement of fractional flow reserve.
