New Treatment for Calcified Coronary Artery Disease

Lake Charles Memorial Hospital is the first hospital in Louisiana to use a new treatment option for patients with severely calcified coronary artery disease. The new technology is a novel application of lithotripsy, an approach that uses sonic pressure waves to safely break up kidney stones. It’s now available to treat problematic calcium in the coronary arteries that can reduce blood flow in the heart.

Heart disease is the leading cause of death for both men and women. Each year, more than 600,000 people in the United States die of the condition. As people with heart disease grow older and their disease progresses, plaque in the arteries evolves into calcium deposits, which can narrow the artery. Physicians often use stents to open an artery, and of the approximately one million patients that undergo a stent procedure each year, 30 percent have problematic calcium that increases their risk for adverse events.

Calcium makes the artery rigid and more difficult to reopen with conventional treatments, including balloons, which attempt to crack the calcium when inflated to high pressure, and atherectomy, which drills through the calcium to open the artery. While atherectomy has been available for several decades, its use remains low, as it can result in complications for patients who are undergoing stent procedures. The new shockwave technology, also known as intravascular lithotripsy or IVL, allows physicians to fracture the problematic calcium - using sonic pressure waves - so that the artery can be safely expanded, and blood flow is restored with the placement of a stent and without unnecessary complications.
