A black and white response to the "gray zone" for fractional flow reserve measurements.
Petraco et al. (1) raise a universal issue that affects all clinical tests. Every binary cutoff produces cases just on either side of the threshold for whom a repeat measurement might alter the decision, no matter how accurate the test or how small its variability. By analogy to a Gaussian distribution of observations about the true value, the critical measure for any diagnostic test remains th...

Without exaggeration, his work is perfect, and his depiction is a masterpiece of the age.” These were the words of Emperor Jahangir of the Mughal Dynasty of India. “Abu’l Hasan’s fathe...
متن کاملFractional Flow Reserve
Traditionally, coronary artery disease was assessed using coronary angiographic guidance. Significant lesions were determined by the coronary angiographer. However, interobserver variability showed a significant limitation of interpretation of coronary angiography. Stent deployment and apposition were also evaluated based on angiographic appearance only. Risk factors for stent thrombosis and in...
متن کاملCerebrovascular research: the opportunity has never been better.
IN LESS THAN FIFTY YEARS, cerebrovascular research has changed from a predominantly morphological and clinical descriptive science to one characterized by the use of the tools of modern cellular biology and clinical investigation. In addition, the brain and its blood supply in health and in disease are now recognized as a unique biological entity for which vascular models in other parts of the ...
متن کاملLong-term outcome after deferral of revascularization in patients with intermediate coronary stenosis and gray-zone fractional flow reserve.
BACKGROUND A strategy of deferred percutaneous coronary intervention for coronary stenosis with fractional flow reserve (FFR) 0.75-0.80, termed the gray zone, remains a matter of debate. The aim of this study was to assess the safety of deferring revascularization for patients with FFR 0.75-0.80 compared with those with FFR >0.80. METHODS AND RESULTS We assessed 3-year clinical outcome in 150...
