Key result

Paradise ultrasound catheter reduces SBP by ~6 mmHg versus sham controls.

Why the study?

Renal denervation represents a new dimension to hypertension treatment with devices seeking FDA approval, spurring interest into its efficacy, safety, and underlying mechanisms.

Overview

Supports Paradise renal denervation for SBP reduction; leaves open standardization across devices amid mixed evidence.

Structured PICO

Does renal denervation reduce systolic blood pressure in individuals with hypertension?

P
Population
Individuals with hypertension
I
Intervention
Renal denervation (including ultrasound Paradise Catheter system and Symplicity Spyral system)
C
Comparator
Sham controls
O
Outcome
Reduction in systolic blood pressure (SBP)surrogate

Renal denervation demonstrates a robust antihypertensive effect, particularly when antihypertensive medications are withdrawn, though results vary across different trials and devices.

Limitations

  • In the SPYRAL HTN-ON MED trial, the sham group experienced a larger medication burden than the denervated group

Cite This Study

Drawz et al. (2023) studied this question. The ultrasound Paradise Catheter system achieved a significant 6.3 mmHg reduction in SBP compared to sham controls, highlighting its antihypertensive efficacy.
