rotational atherectomy

Rotational atherectomy is a medical procedure used to treat narrowed or blocked coronary arteries. A small, high-speed rotating burr is inserted into the artery to precisely grind away plaque buildup, which is made of fat, calcium, and other materials. This helps restore blood flow to the heart muscle. The procedure is typically performed when the plaque is too hard or calcified for standard treatments. It’s minimally invasive, usually done through a catheter, and helps improve heart function and reduce symptoms like chest pain, enhancing overall cardiovascular health.
