MARIN-OROZCO, Isabel C. et al. Percutaneous renal denervation using balloon catheter in patients with resistant hypertension. Rev. Colomb. Cardiol. [online]. 2015, vol.22, n.6, pp.305-311. ISSN 0120-5633.  https://doi.org/10.1016/j.rccar.2015.08.002.

Hypertension affects more than 1,200 people in the world, and constitutes one of the most important risk factors for the incidence of acute myocardial infarction and cerebrovascular accident. Only 35% of hypertensive patients show controlled blood pressure (BP) values with the use of hypertensive drugs. Al alternative becomes available: renal denervation as an invasive technique. It has shown to significantly reduce the BP levels in patients with resistant hypertension, and though it was discussed and controversial after the publication of the SYMPLICITY HTN-3 trial, where no significant reduction of BP values using the ambulatory blood pressure monitoring (ABPM) was noted, many questions have yet to be answered regarding this new technique and its application in the clinical field. The motivation for this report is to accurately describe two cases of resistant hypertension treated with radiofrequency ablation with the new Vessix^® device from the company Boston Scientific.
