First seen Jan 06, 2026 · Last updated Jun 24, 2026 · Updated 25 times
Summary
This study looks at three ways to treat severely hardened heart arteries before placing a stent: using sound waves (lithotripsy), a high-pressure balloon, or a tiny rotating device (orbital atherectomy). The goal is to see how each method affects the small blood vessels in the heart. Thirty people with heart disease will be assigned to one of the three treatments, and doctors will measure blood flow and vessel resistance before and after the procedure.
