Figure 1: Renal Denervation Procedure and Histological Assessment

(A) Renal angiogram of left renal artery in anteroposterior view before renal denervation (RD). (B) A 5-F quadripolar multiple electrode array ablation catheter (EnligHTNTM, St. Jude Medical, St. Paul, Minnesota) that consists of an expandable basket with 4 electrodes was used for RD. (C) An example of acute gross histology after RD to show the placement of lesions inside the renal artery. (D) Percentage area of left ventricular infarct as measured by histological examination in the control group (n = 10) and RD group (n = 10).
