It has long been known that patients recover more quickly from transcatheter aortic valve replacement (TAVR) than from open-heart surgery for valve replacement (SAVR) and results at two years looked good, too, with very similar outcomes. The question remained what happens in the longer term?

A new study has found that despite the risk, many patients are open to interventional procedures such as renal denervation (RDN) if it can lead to improved blood pressure. RDN is performed under local anesthetic and uses radio frequency ablation to burn the nerves in the renal arteries. The process causes a reduction in nerve activity, which decreases blood pressure.
