May 10, 2025 updated by: Yuehui Yin, The Second Affiliated Hospital of Chongqing Medical University

Efficacy and Safety Comparison of Renal Sympathetic Denervation Combined With Aorticorenal Ganglion Ablation vs. Renal Sympathetic Denervation Alone for the Treatment of Hypertension: A Multicenter, Prospective, Proof-of-concept Cohort Trials.

The purpose of this prospective cohort proof-of-concept trial is to compare the efficacy and safety of renal sympathetic denervation (RSD) plus aorticorenal ganglion ablation versus RSD alone in the treatment of uncontrolled primary hypertension.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Currently, renal sympathetic denervation (RSD) has become the "third pillar" of hypertension treatment, following lifestyle interventions and pharmacological therapy. However, it still faces challenges such as limited and unstable blood pressure-lowering effects. One of the key factors contributing to the poor efficacy of the procedure is inadequate renal sympathetic nerve ablation, which is influenced by the complex renal artery anatomy and nerve network distribution. From a neuroanatomical perspective, aorticorenal ganglion (ARG) is a crucial hub for sympathetic nerve projection to the kidneys. We hypothesize that on the basis of RSD, additional ablation of aorticorenal ganglion can enhance the BP-lowering effect in patients with uncontrolled primary hypertension. Therefore, we plan to design the first multicenter, prospective, cohort, proof-of-concept trial to compare the efficacy and safety of RSD plus ARG ablation (ARGA) versus RSD alone in the treatment of uncontrolled primary hypertension.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Active Comparator: RSD group
High-frequency stimulation (HFS) guided radiofrequency ablation from accessible branches to the opening of the renal artery.
Procedure: Renal sympathetic denervation
Under the guidance of the 3-dimensional navigation system, HFS was performed from the accessible branches to the proximal (the ostium of renal artery) segments of the bilateral renal arteries, and the target ablation sites were identified by HFS-induced SBP elevation >5mmHg, and radiofrequency ablations were performed with a power setting of 8 to 12 Watts and a duration of 90 seconds. The endpoint of RSD was defined as the elimination or bluntness of HFS-induced SBP elevation response (≤5mmHg). If this was not achieved, ablation was repeated until the desired response was attained.
Experimental: RSD+ARGA group
High-frequency stimulation (HFS) guided radiofrequency ablation from accessible branches to the opening of the renal artery, as well as HFS-guided ARG ablation.
Procedure: Renal sympathetic denervation plus aorticorenal ganglion ablation
Following RSD, HFS was performed in the the junction area of abdominal aorta and renal arteries to recognize ARG. Radiofrequency ablations were performed with a power setting of 12 to 20 Watts and a duration of 90 seconds. The endpoint of ablation was defined as the elimination or bluntness of HFS-induced SBP elevation response (≤5mmHg). If this was not achieved, ablation was repeated until the desired response was attained.
