ZACHARY, LA– Cardiovascular Institute of the South (CIS) is the first in Zachary to use a new lithotripsy balloon by Shockwave Medical, Inc. to treat peripheral artery disease (PAD), a condition where plaque builds in the arteries of the legs and leads to blockage. The first use was performed by CIS interventional cardiologist Dr. Nayan Agarwal at Lane Regional Medical Center.

Lithotripsy is an innovative advanced technology that uses sonic pressure waves to break up hardened calcium buildups so that blockages can be removed, and blood flow can be restored. This technology creates a series of micro-fractures in the calcium, and the balloon expands the vessel, enabling blood flow. This therapy uses a similar minimally-invasive approach that has been used by physicians for decades to treat kidney stones, which are also made up of calcium.

Agarwal-WebThe technology was used to treat a critical stenosis in abdominal aorta, a condition which is typically treated with open surgery and several days of hospitalization. Dr. Agarwal used this new technology to place a stent to open the blockage, without the need for major surgery, and the patient was discharged the same day. “We are proud to be the first to offer this innovative technology to the patients of Zachary,” said Dr. Agarwal. “These sonic pressure waves offer a safe and proven treatment option for patients suffering from blockages in the legs, with a lower risk of complications.”

Aorta Stent

PAD affects more than 12 million people in the United States by preventing blood flow to the legs and feet, causing significant pain and limited mobility, and potentially leading to surgery or even amputation in severe cases. Symptoms of PAD in the legs include: pain or cramping after activity, numbness, coldness, sores or ulcers that won’t heal, discoloration, hair loss, shiny skin or a weak pulse.
