OPELOUSAS, LA– Cardiovascular Institute of the South (CIS) is the first in Acadiana to use a new lithotripsy balloon by Shockwave Medical, Inc. to treat coronary artery disease, a condition where calcified plaque builds up in the coronary arteries. The first use was performed by CIS interventional cardiologist Dr. Kalyan Veerina at Opelousas General Health System.

The new technology is a novel application of lithotripsy, an approach that uses sonic pressure waves to safely break up kidney stones. In this case, the shockwave technology allows physicians to create micro-fractures in the hardened calcium to break it up, with the balloon expanding the vessel and restoring blood flow.

“This latest treatment is a game changer for patients with severe calcified plaque in the coronary arteries,” explained Dr. Veerina. “This is a safe and proven treatment option with a lower risk of complications than conventional treatments like atherectomy and high-pressure balloons, and we are proud to offer it at CIS and Opelousas General.”
