Minimally Invasive Technology to Help Control High Blood Pressure is Now Available in Sumner County

Dec. 11, 2025 – Highpoint Health – Sumner with Ascension Saint Thomas performed the first renal denervation (RDN) procedure in Sumner County recently. This procedure is for certain patients with high blood pressure. 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 medications do not adequately control blood pressure.

Hypertension is the single largest contributor to death, according to the World Health Organization, and affects about 50% of U.S. adults, says the U.S. Department of Health and Human Services. Of the U.S. adults who are aware of their hypertension, about 80% do not have it under control. This procedure can help reduce high blood pressure, which can lower serious health risks.

How does it work:

• A patient is given mild sedation and taken to the cardiac catheterization lab (known as a cath lab)
• The doctor inserts a very thin tube into the artery leading to the kidney.
• The doctor 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 significant problem for patients. For people with hypertension, medication and/or lifestyle changes can help reduce blood pressure, but studies have shown that many people still don’t have control over their condition,” said Dr. Gary “Beau” Yawn, the Ascension Saint Thomas Heart cardiologist who did the first procedure at Highpoint Health – Sumner in Gallatin.

“The Symplicity blood pressure procedure can provide patients with a blood pressure reduction benefit that is ‘always on’ and doesn’t require a permanent implant – it can also help patients regain their peace of mind. We are looking forward to the future of hypertension care and are proud to be offering innovative solutions without the burden of having to travel to Nashville. This is high quality heart care close to home.”
