NEW IBERIA – Cardiovascular Institute of the South (CIS) is using a new lithotripsy balloon by Shockwave Medical, Inc. to treat coronary and peripheral artery disease (PAD) at Iberia Medical Center (IMC). The first Shockwave treatment at IMC was performed by interventional cardiologist Dr. Krishna Nagendran.

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.

“This technology delivers pulses of sonic pressure to break the calcium in artery blockages,” explained Dr. Nagendran. “It is a game changer for our patients to have this new safe and effective treatment available in New Iberia, particularly for those who suffer from chronic peripheral artery disease in the legs.”

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.
