Eligibility Criteria
You may qualify if:
- Either
- Documented history of hypertension on two or more anti-hypertensive medications OR
- Renal dysfunction, defined as Stage 3 or greater chronic kidney disease (CKD) based on the new National Kidney Foundation (NKF) classifications (estimated glomerular filtration rate \[GFR\] less than 60 mL per minute per 1.73 m\^2, calculated by the modified Modification of Diet in Renal Disease \[MDRD\] formula)
- One or more severe renal artery stenoses by any of the following pathways:
- a. Angiographic: greater than or equal to 60% and less than 100% by renal angiogram OR b. Duplex: systolic velocity of greater than 300 cm/sec OR c. Core Lab approved Magnetic Resonance Angiogram (MRA) (refer to the protocol for specific criteria) demonstrating stenosis greater than 80% OR stenosis greater than 70% with spin dephasing on 3D phase contrast MRA OR stenosis greater than 70% and two of the following: i. Ischemic kidney is greater than 1 cm. smaller than contralateral kidney ii. Ischemic kidney enhances less on arterial phase iii. Ischemic kidney has delayed Gd excretion iv. Ischemic kidney hyper-concentrates the urine v. 2-D phase contrast flow waveform shows delayed systolic peak vi. Post-stenotic dilatation d. Clinical index of suspicion combined with a Core Lab approved Computed Tomography Angiography (CTA) demonstrating Stenosis is greater than 80% by visual assessment on high quality CTA Stenosis is greater than 70% on CTA by visual assessment and there are two of the following i. The length of the ischemic kidney is greater than 1 cm. smaller than contralateral kidney ii. Reduced cortical thickness of ischemic kidney iii. Less cortical enhancement of ischemic kidney on arterial phase iv. Post-stenotic dilatation
