title: Preductal aortic coarctation and patent ductus arteriosus in a Sumatran tiger (Panthera tigris sumatrae) cub.
abstract: Preductal aortic coarctation and patent ductus arteriosus are described in a neonatal Sumatran tiger, Panthera tigris sumatrae. Eight days postpartum, the cub appeared weak, and it was separated from the dam for hand rearing. On examination it was dehydrated and hypothermic. Despite treatment, the animal's condition worsened and the cub died 12 days postpartum. Gross postmortem and histologic examinations revealed a preductal aortic coarctation and patent ductus arteriosus with a patent foramen ovale and moderate dilatation of the right ventricle of the heart. Focal pneumonia and mild hepatitis were also present; however, diffuse pulmonary congestion and edema were considered to be the proximate cause of death.
