Safety and Efficacy of Modulated Ultrasound Renal Denervation for HTN
China204 participantsStarted 2025-01-25
Plain-language summary
Prospective, multicenter, randomized, controlled, blinded, and superiority - designed; The target population undergoes a screening treatment with prescribed medications for at least 4 weeks. Eligible subjects are randomly assigned to the experimental group and the control group at a ratio of 2:1. The experimental group is treated with the ultrasound nerve ablation catheter and the ultrasound nerve ablation device of Shenzhen Maiwei Medical Technology Co., Ltd., while the control group only undergoes renal arteriography (regarded as a sham operation). Within 6 months after the operation, both groups continue to receive antihypertensive drug treatment with the dosage and types specified during the screening period. The subjects are kept blinded during the study. The relative change values of the average 24 - hour ambulatory systolic blood pressure from the baseline at 6 months after the operation are compared between the two groups.

Inclusion criteria
✓. Age between 18 and 70 years old (calculated based on the date of starting standardized medication).
✓. After treatment with at least two types of antihypertensive drugs for 4 weeks or more, the clinic systolic blood pressure is ≥140 mmHg and ≤180 mmHg, and the average 24 - hour ambulatory systolic blood pressure is ≥130 mmHg (or the daytime ambulatory systolic blood pressure is ≥135 mmHg).
✓. Resting heart rate ≥70 beats per minute without taking beta - blockers (this criterion does not apply to patients taking beta - blockers).
✓. The subject agrees to participate in this clinical trial, complies with the follow - up required by the trial protocol, and has voluntarily signed the informed consent form
Exclusion criteria

CTA, MRA, or DSA examination shows that the shape and structure of the unilateral or bilateral renal arteries are not suitable for ablation surgery (renal artery stenosis exceeding 50%, renal artery aneurysm, fibromuscular dysplasia of the renal artery, or the diameter of the main renal artery is less than 3 mm).
✕. Having only one kidney or having received a kidney transplant.
