Guidelines for renal denervation in hypertension.
Abstract
The Society for Cardiovascular Angiography and Interventions (SCAI) has released a draft guidance on renal denervation (RDN) for hypertension refractory to medical therapies. The draft addresses patient selection, procedural techniques, operator competence, training, and hospital guidance for RDN adoption. Feedback is requested by June 14. RDN disrupts sympathetic nerves near renal arteries and has shown short-term blood pressure reductions. The draft emphasizes the need for clinical competence, training standards, and best practices for RDN.
Patient Selection Considerations
- RDN effectiveness varies with patient age and arterial stiffness.
- Patients with limited treatment options may benefit most.
- Response to RDN varies, with predictors like baseline systolic blood pressure.
Procedural and Technical Considerations
- Preprocedure evaluation should rule out secondary causes of HTN.
- Anatomic considerations and imaging modalities are crucial for RDN success.
- Operators need training in access, catheters, and troubleshooting.
Training, Competency, and Institutional Requirements
- Interventional cardiologists must demonstrate proficiency in various skill sets.
- Institutions offering RDN need a dedicated HTN program and a multidisciplinary team.
- Requirements for RDN referral centers include experienced operators and appropriate infrastructure.
Stats
"The draft addresses appropriate patient selection, best practices for procedural techniques, measures for operator competence, recommendations for operator and staff training, and guidance for hospitals and centers that want to adopt RDN."
"Two devices are awaiting FDA premarket approval: the Paradise uRDN system, by ReCor Medical; and the Symplicity Spyral device, by Medtronic."
"The first sham-controlled randomized trial of RDN was negative on its primary endpoint."
