Bruit, also called vascular murmur,[3] is the abnormal sound generated by turbulent flow of blood in an artery due to either an area of partial obstruction or a localized high rate of blood flow through an unobstructed artery.[4]
The bruit may be heard ("auscultated") by securely placing the head of a stethoscope to the skin over the turbulent flow, and listening. Most bruits occur only in systole, so the bruit is intermittent and its frequency dependent on the heart rate. Anything increasing the blood flow velocity such as fever, anemia, hyperthyroidism, or physical exertion, can increase the amplitude of the bruit.

Etymology
It is naturalized from the French word for "noise", although another notes that /ˈbruːi/ and /bruːˈiː/ are also common,[5] and others give only /ˈbruːi/ for the cardiac sense.[6][7]

A 4-month-old intact female Cavalier King Charles spaniel presented for evaluation of a left, basilar continuous murmur. Transthoracic echocardiography suggested anomalous vessels around the main pulmonary artery, and computed tomography angiography revealed two systemic-to-pulmonary artery fistulas

Pericardial, myocardial, and great vessel diseases are relatively rare in horses. The clinical signs are often nonspecific and vague, or related to the underlying cause. Physical examination usually reveals tachycardia, fever, venous distension or jugular pulsation, a weak or bounding arterial pulse
Repair of Anomalous Right Coronary Artery From the Pulmonary Artery Using the Modified Trapdoor Technique.

World journal for pediatric & congenital heart surgery. 2019 03;10(2)192-196.
Anomalous origin of the right coronary artery from the pulmonary artery (ARCAPA) is rare. Unique anatomical characteristics observed include tethering secondary to the extensive collateral vessels, severe native coronary tortuosity, and massive dilation of the coronary arteries. This requires specif
