Utility of transesophageal echocardiography in the diagnosis of tetralogy of fallot in a dog

Abstract

Tetralogy of Fallot (ToF) is an uncommon complex congenital cardiac defect in dogs and cats. Its incidence in dogs has been reported to be 0.0025% [1,2]. Transesophageal echocardiography (TEE) can be valuable in diagnosis and accurate study of complex congenital heart defects in human medicine, but there is limited data on this subject in veterinary medicine [3]. Thus, we reported here utulity of TEE compared with trans-thoracic echocardiography (TTE) for the diagnosis of ToF in a dog.
