CONTROL-HTN: Mechanical device improved BP in patients with resistant arterial hypertension

November 21, 2014

Read the Perspective from Michael R. Jaff, DO

Patients with treatment-resistant arterial hypertension had significant reductions in office-measured and ambulatory BP following arteriovenous anastomosis with a mechanical device, according to results from the CONTROL-HTN study presented at VIVA 14.

Researchers for the prospective, controlled, blinded, multicenter study evaluated 83 patients with treatment-resistant hypertension. The patients were randomly assigned to undergo arteriovenous anastomosis with the Rox Coupler (Rox Medical), a mechanical device designed for the treatment of arterial hypertension, or a control procedure. During treatment, the nitinol Rox Coupler is placed to create a fixed arteriovenous anastomosis between the artery and external iliac vein to improve arterial compliance and decrease vascular resistance.
