    When heard through a stethoscope, turbulent blood flow produces a murmur as blood tumbles over an abnormal heart valve. A similar sound called a bruit is heard as blood goes through a narrowed or irregular artery. A bruit indicates that atherosclerosis, which is a major risk factor for TIAs, is present.
