Abstract:
A fibrous band connecting the middle of the free edge (nodulus Arantii) of the non-coronary aortic valve cusp to the ascending aorta just above the level of the non-coronary sinus of Valsalva was observed in an asymptomatic, 11-year-old, male Border Collie. The fibrous band was unrelated to the cause of the death in this dog. Such fibrous bands are usually reported in humans with congenital bicuspid aortic valves. To our knowledge, this is the first report of a fibrous band in the aortic valve in a domestic animal.
