Abstract

A key assumption in the physiological assessment of coronary stenosis in the MR-INFORM (Myocardial Perfusion CMR versus Angiography and FFR to Guide the Management of Patients with Stable Coronary Artery Disease) trial by Nagel et al. (June 20 issue)1 is that the two catheter systems used to measure the pressure gradient across a coronary stenosis are identical with respect to calibration and zero level. The article and Supplementary Appendix (available with the full text of the article at NEJM.org) do not provide this assurance.
