Answer

Based on an expert panel review of scientific data, the SCAI concluded that patients with the following are most likely to benefit from renal artery stenting [58] :

  • Cardiac disturbance syndromes (flash pulmonary edema or acute coronary syndrome)
  • Hypertension that has not been controlled by three or more medications at maximal tolerated doses
  • Blockages in both kidneys or severe blockages in a single functioning kidney where blood pressure or renal dysfunction cannot be managed medically

The SCAI concluded that patients with any of the following are typically not good candidates for renal artery stenting [58] :

  • Mild or moderate blockages (less than 70%)
  • Long-standing loss of blood flow
  • Complete blockage of the renal artery
