Echocardiography for the diagnosis of congenital heart defects in the dog

Echocardiography utilizing M-mode and real-time techniques is a safe, noninvasive diagnostic technique for use in veterinary cardiology. It provides a means to assess structural sizes and relationships and can be used to provide quantitative data for diagnosis of congenital heart disease. Although its availability is largely limited to veterinary colleges and specialty hospitals, the practicing veterinarian should know of its advantages and disadvantages. He or she is also encouraged to consider the use of ultrasound in the diagnosis and management of heart disease in all species of veterinary patients.
