Interventions/Control_1

All participants undergo percutaneous transluminal catheter radiofrequency ablation in renal artery with 5Fr ablation catheter approved for treating cardiac arrhythmia. Initial 3 cases undergo 4W x 60sec ablation for 4 points. If they do not achieve mean systolic blood pressure reduction of over 10mmHg at 1 months later, another 3 cases undergo 6W x 60sec ablation for 4 points.
