Left atrial insertion of the cranial (i.e., superior) and caudal (i.e., inferior) venae cavae is a rare disorder in humans and is unreported in the domestic dog (Canis lupus familiaris). In humans, it most often manifests as unexplained cyanosis in patients without other signs of heart disease. Herein, we report the case of a young French bulldog presented with cyanosis and marked exercise intolerance, in which a diagnosis of left atrial drainage of the cranial and caudal venae cavae was made, with an atrial septal defect (ASD) and aorticopulmonary collateral vessels.
