What did the CORAL trial show?

CORAL trial (2014): in atherosclerotic renal artery stenosis (>=60% stenosis), stenting plus medical therapy vs medical therapy alone showed no significant difference in composite cardiovascular/renal outcome at 43 months.

When might renal artery stenting still be considered?

Stenting may be considered for: flash pulmonary edema with bilateral RAS, resistant hypertension with high-grade RAS and functional significance (FFR <0.90), and rapidly declining kidney function from bilateral RAS.

How is renal artery stenosis classified?

=70%: significant. Bilateral RAS or RAS to solitary kidney warrants urgent evaluation.
