An Atherectomy is a procedure for removing plaque from an artery (blood vessel). Removing plaque makes the artery wider, so the blood can flow more freely to the heart muscles. During the procedure, the plaque is shaved or vaporized with tiny rotating blades or through a laser on the end of a catheter. During the procedure, the surgeon uses a revolving instrument for breaking up a calcified plaque that is clogging a coronary artery. Breaking up the plaque restores blood flow to the heart. The right specialist to consult for a Rotational Atherectomy is an experienced Interventional Cardiologist. The success rate for the treatment remains around 64-76%.
