Hypertension is the leading cause of mortality worldwide. Effective therapies are needed for resistant hypertension, a common condition characterized by inadequate blood pressure control despite 3 or more medications, which is associated with increased cardiovascular mortality. ⋯ Initial studies have demonstrated procedural safety and effectiveness in blood pressure reduction up to 2 years after procedure. Large randomized control trials are necessary and currently underway to define further the role of renal denervation and long-term consequences in the treatment of resistant hypertension.
