Hypertension is the most prevalent cardiac risk factor. In the United some estimates show 60% of 60-year-olds, 70% of 70-year-olds, an 80% of 80-year-olds being hypertensive. Often, blood pressure becomes resistant or refractory. Device therapy represents a new approach to treating this disease. The best studied of these nonpharmacologic approaches to resistant/refractory hypertension include renal denervation, carotid sinus stimulators, and central arteriovenous fistula placement. This chapter will focus on novel device therapy and literature review of its use in clinical trials.
