Abstract
catheter was inserted (Simplicity Flex) inside the renal artery, allowing the delivery of radiofrequency energy to the renal artery innervation. Radiofrequency applications were performed within the main stem of the renal arteries, bilaterally, with a series of 6 applications, 60 s duration each. At the end of the procedure, renal arteriography was performed for evaluation of vascular integrity. Results: Data were obtained at baseline and monthly until 180th day of follow-up. Baseline values of blood pressure were 196/122 mmHg in the office, and 164/109 mmHg by 24h ABPM. The decreased of ABPM data was 47/38mmHg, achieving values of 117/71mmHg with 14 days after procedure (figure 1), with the same average at 180th day, reducing from 7 to 3 antihypertensive drugs in 6 months. The procedure was performed without complications. Conclusions: Renal sympathetic denervation using the irrigated radiofrequency ablation catheter was effective in a patient with resistant hypertension.
