文摘The highly diagnostic performance of renal transstenotic pressure gradients （TSPG） and fractional flow reserve （FFR） has been well validated for assessment of the hemodynamic renal artery stenosis （RAS）.1-4 Accordingly,an expert consensus panel of the American Heart Association recommended that a peak systolic gradient of at least 20 mmHg （1 mmHg=0.133 kPa）,or a mean pressure gradient of 10 mmHg,be used to identify candidate lesions for revascularization in symptomatic patients with RAS.
