• Hemodynamically significant asymptomatic (incidental) RAS (is defined as:
1. 50% to 70% diameter stenosis by visual estimation with a peak translesional
gradient (measured with a ≤5F catheter or pressure wire) of 20 mm Hg or higher
or a mean gradient of 10 mm Hg orhigher; OR
2. any stenosis with 70% or larger diameter by visual estimation; OR
3. stenosis with 70% or larger diameter by intravascular ultrasound measurement

as a decrease in estimated glomerular filtration rate to less than 60
mL/min per 1.73 m2 (modified Modification of Diet in Renal Disease
formula) that persists for at least 3 months
• Studios with a baseline serum creatinine between 1.5 and 4.0 mg per dL
• Several factors may argue against
– proteinuria greater than 1 g every 24 hours renal atrophy,
– severe renal parenchymal diseas disease, and severe diffuse
– intrarenal arteriolar disease.
