Use of contrast enhanced magnetic resonance angiography in assessment of anatomic suitability for renal denervation in the hypertensive population

Background Renal denervation (RDN) is an effective treatment for resistant hypertension with expanding indications in the hypertensive population [1]. The European Society of Hypertension (ESH) guidelines [2], largely based on the Symplicity trial inclusion criteria, state RDN should not be performed if the patient has multiple renal arteries, renal artery stenosis or renal arteries with a diameter of less than 4 mm or length of less than 20 mm. Imaging prior to consideration of RDN is recommended but has not been included in all RDN trial protocols. The proportion of hypertensive patients with anatomy suitable for RDN using the current guidelines is not known.
