BACKGROUND Effective treatment of uncontrolled hypertension using catheter-based percutaneous renal denervation may depend strongly on the anatomic strategy applied when delivering therapy. We hypothesized that concentering renal denervation treatment in the distal region of the artery would improve clinical response. METHODS AND RESULTS We conducted a(More)
AIM to define and develop a procedure that can select patients with resistant hypertension (RH) for a renal sympathetic denervation (RSD) procedure, by being orienting to the specific initial values of β-adrenoreactivity (β-AR) and systolic blood pressure (SBP). SUBJECTS AND METHODS The analysis included 23 RH patients receiving the maximally tolerable(More)
OBJECTIVE A failure of endovascular renal denervation (RDN) as a series of point treatments equally distributed within main trunk of renal artery (Symplicity and other methods) was easily predictable. It may only be effective if all renal nerves closely follow the course of renal artery (RA) from aorta to the kidney. However, surgical studies demonstrated(More)
OBJECTIVE Surgical and recently anatomical studies demonstrated a fan-like form of renal plexus converging toward renal gate. Therefore, a number of fibers adjacent to the artery and available for endovascular ablation is rather small in proximal portion of renal artery but grows to maximum in its distal part. To evaluate whether denervation treatment in(More)
