What this trial studies

This is a prospective, multi-center, single-arm, non-interventional registry aimed at documenting the long-term safety and effectiveness of renal denervation in patients with hypertension. Approximately 5000 patients will be enrolled from over 300 sites worldwide, with follow-up ranging from 1 to 5 years post-procedure. Data collected will include blood pressure measurements, medication changes, and clinical data related to hypertension. The registry will help expand the knowledge base regarding the Medtronic renal denervation system in a real-world patient population.

Who should consider this trial

Good fit: Ideal candidates for this registry are adults aged 18 and older with uncontrolled hypertension who are suitable for renal denervation.

Not a fit: Patients with controlled hypertension or those not eligible for renal denervation may not benefit from this registry.

Why it matters

Potential benefit: If successful, this registry could provide valuable insights into the long-term management of hypertension through renal denervation.

How similar studies have performed: Other studies on renal denervation have shown promise, suggesting that this approach may be effective in managing hypertension.
