A quantitative method of cardiac measurement, called the vertebral heart scale, has been devised to take into account the inherent breed variation in cardiac size. In this chapter, the qualitative radiographic signs of enlargement are discussed for each heart chamber, the aorta, and the caudal vena cava. This dog also has left atrial dilation that causes a concavity on the dorsocaudal heart border (white arrow).ĭespite these normal variations, a starting point for radiographic evaluation is necessary. The less opaque fat creates contrast for visualization of the real margin of the heart (black arrows). ![]() There is fat around the heart in the mediastinum, leading to the cardiac silhouette being larger than the heart itself. 32-3 Lateral radiograph of the thorax of a Doberman pinscher. If any suspicion of a cardiac abnormality exists, because of either radiographic appearance or clinical or historical information, then echocardiography should be performed. Thus the breed and body physique of the dog should always be considered when the heart is evaluated radiographically. Conversely, the normal heart in breeds with a laterally compressed but deep thoracic cavity, such as greyhounds and collies, can look abnormally small (Fig. With regard to the wide range of the normal cardiac appearance, muscular dogs or those with a barrel-shaped thorax often have a heart that looks large. 1- 4 See Chapter 25 for a comprehensive discussion of these issues Unfortunately, radiographs are not very accurate for assessing either cardiovascular function or morphology because the range of the normal cardiac appearance is very wide in dogs and the appearance of the cardiac silhouette is affected by radiographic positioning. When possible, we use a technique that causes less strain on your body: a stent-graft.Assessing cardiovascular function becomes important when decisions must be made regarding staging a patient with suspected cardiac disease, deciding about therapy, and monitoring response to therapy or progression of disease. ![]() Stent-Graft Surgery: Results With Less Strain Procedures or surgery: Whether you need a procedure or surgery depends on the size of your aneurysm or if it’s changing.
