Procedural Sedation in Renal Sympathetic Denervation
This retrospective, single-center study investigates the effects of two different sedation regimens-dexmedetomidine versus fentanyl-propofol-on clinical outcomes in patients undergoing catheter-based renal sympathetic denervation for resistant hypertension. The study focuses on peri-procedural safety, recovery, and overall tolerability of sedation approaches in this interventional setting.

INtraprocedural Feedback-Optimized Renal Denervation Based on Measurements Obtained Through Renal Artery Stimulation: a Randomized Controlled Trial (INFORM)
Our previous study (Huang HC, Pan HY, Wang TD, Circ Cardiovasc Interv 2023;16:e012779) demonstrated that when renal artery stimulation continues to trigger systolic blood pressure increases (\>=20 mmHg increase compared to baseline) after the initial procedure, patients show poor blood pressure reduction 6 months following renal denervation. Based on this finding, we designed a proof-of-concept trial comparing two approaches: a guided strategy versus conventional renal denervation. In the guided strategy, we perform additional ablations of main and/or branch renal arteries if immediate post-procedure stimulation still elevates systolic blood pressure (\>=20 mmHg increase compared to baseline). The conventional approach involves no repeat procedures. This trial aims to determine whether the guided strategy leads to better clinical outcomes, measured by 6-month ambulatory blood pressure changes, and to establish the value of using intraprocedural feedback to assess and guide renal denervation treatment.
