Safety and Efficacy of Renal Denervation for Untreated Grade I Hypertension: a Pilot Study (STAR)
Safety and Efficacy of Six-Channel Radiofrequency Ablation System for Renal Denervation in Patients With Untreated Grade I Hypertension: a Pilot Study
Panoramica dello studio
Stato
Condizioni
Descrizione dettagliata
The six-channel RF renal denervation system, consisting of the six-channel RF generator (specification model: 25D1G, software release version: SRG-V1) and the disposable ultra-guiding RF denervation catheter (specification model: 25C6W127F115T), is designed and manufactured by Shanghai Golden Leaf MedTec Co., Ltd (BRATTEA) for renal artery RF denervation.
This Prospective, Multi-Center, Randomized, shame-controlled uptake clinical trial aims to evaluate the system's efficacy and safety for renal denervation in patients with grade I hypertension and without taking antihypertensive medicines, and to provide clinical evidence supporting the expansion of indications. The trial will be conducted by the Regulations on the Supervision and Administration of Medical Devices, the Measures for the Administration of Medical Device Registration and Filing, the Good Clinical Practice for Medical Devices, and other applicable requirements.

Sperimentale: Renal denervation
Participants receive percutaneous renal sympathetic denervation under digital subtraction angiography (DSA) guidance using a six-channel radiofrequency generator(model 25D1G, software release SRG-V1) and ultra-guiding radiofrequency denervation catheter (model 25C6W127F115T) manufactured by Shanghai Golden Leaf MedTec Co., Ltd(BRATTEA).
All participants receive a standardized antihypertensive regimen for ≥4 weeks before the procedure and thereafter per protocol.
Follow-up visits occur at 7 days or before discharge, and at 1 and 3 months.

|
|
Comparatore fittizio: Parallel control with sham operation
Participants undergo a sham procedure: femoral artery puncture and selective renal angiography under DSA guidance are performed.
The RF generator is connected to a dummy load, and activation sounds are emitted, but no energy is delivered.
Participants remain on the procedure table for at least 35 minutes before sheath removal.
Background standardized antihypertensive therapy is provided for ≥4 weeks pre-procedure and continued per protocol.
Follow-up visits occur at 7 days or before discharge, and at 1 and 3months.

Procedura sham, compresa la puntura dell'arteria femorale e l'angiografia renale selettiva; Il generatore di radiofrequenza a sei canali è collegato a un carico fittizio e produce suoni di attivazione, ma non viene erogata energia.
Il tempo minimo del tavolo prima della rimozione della guaina è di 35 minuti.
