MarinHealth Interventional Cardiologists Are First on the West Coast to Perform Symplicity™ Renal Denervation Procedure Outside of a Clinical Trial

This Revolutionary New Procedure Helps to Control High Blood Pressure

MarinHealth interventional cardiologists treated the first patient with a revolutionary new renal denervation (RDN) procedure, now offered for patients with poorly controlled blood pressure. Recently approved by the U.S. Food and Drug Administration (FDA), the Symplicity Spyral™ renal denervation (RDN) system involves a minimally invasive procedure that targets nerves near the kidneys that can become overactive and cause high blood pressure. The procedure – also known as the Symplicity™ blood pressure procedure – is approved for use as an adjunctive treatment in patients with high blood pressure (or hypertension) when lifestyle changes and antihypertensive medications do not adequately control blood pressure.

Hypertension is the single largest contributor to death,¹ and affects about 50% of U.S. adults.² Of the U.S. adults who are aware of their hypertension, about 80% do not have it under control.³

“We’re so excited to be the first on the West Coast to offer this innovative treatment option right here in Marin,” commented chief executive officer David Klein, MD. “Thanks to the generosity of Reta and Bill Haynes through their family foundation, we can help patients find a life-changing option and peace of mind.”

The Symplicity blood pressure procedure is clinically proven to help reduce high blood pressure,^4-6 which can lower serious health risks.⁷ After mild sedation, the interventional cardiologist inserts a very thin tube into the artery leading to the kidney. The doctor then administers energy to calm the excessive activity of the nerves connected to the kidney. The tube is removed, leaving no implant behind.

"High blood pressure is a common problem that is difficult for patients to control. A combination of lifestyle changes, like exercise and weight loss, and medication can help treat high blood pressure safely. However, many patients still lack adequate blood pressure lowering," said interventional cardiologist Robert Sperling, MD. "Renal denervation can help reduce blood pressure in patients with a single, minimally invasive procedure and does not require a permanent implant. We are grateful that we were able to treat this patient, and we look forward to helping more patients with this innovative procedure."

If you or someone you know is experiencing uncontrolled blood pressure, talk to a doctor at the Haynes Cardiovascular Institute to see if the Symplicity blood pressure procedure is a possible treatment option. Visit MyMarinHealth.org/RenalDenervation.
