ABSTRACT

Double outlet right ventricle (DORV) and left ventricle hypoplasia are congenital cardiac defects rarely described in the dog. It is characterized by the great vessels (pulmonary artery and aorta) originating from right ventricle, and the left ventricle lacking development. A clinical case of a four months old female Chihuahua puppy, with clinical history of depression, abnormal cardiac sounds and cyanosis is described. Hemogram, radiology and echocardiogram were performed. The patient died suddenly and the post mortem study revealed DORV and left ventricle hypoplasia. The objective of this report is to portray the clinical findings, hemodynamic changes and anatomopathological findings in this dog, to contribute to the knowledge of this congenital defect barely described in veterinary medicine.
