title: Double-outlet right ventricle associated with discordant atrioventricular connection and dextrocardia in a cat.
abstract: The prevalence of congenital cardiac disease in cats varies from 0.2 to 1 per cent, with males being more affected than females. This is probably an underestimate due to the fact that not all affected kittens are presented. Discordant atrioventricular connection (where the morphological right atrium connects to the morphological left ventricle, and the morphological left atrium connects to the morphological right ventricle) is an uncommon condition in humans and, to the authors' knowledge, has not to date been described in animals. The association between this anomaly and the double-outlet right ventricle (where both great arteries arise entirely or partially from the morphological right ventricle) is extremely rare in children. This report describes a case of a cat which presented with this association of cardiac defects.
