FIG. 2 Summary of initial reported series in terms of improvement of (A) hypertension and (B) renal function after renal artery revascularization. Despite a technical success of >95%, clinical outcomes did not match technical success. This suggests that selection of patients is crucial in order to obtain clinical benefit.
