The cardiovascular diseases of cattle remained challenging for the clinician before classical signs of heart failure appeared. In more advanced stage of heart disease (HD) the differential diagnosis need further ancillary tests than simple physical and clinical examination. Some of these tests can be done under field conditions (blood tests, echocardiography, pericardiocentesis), others are available only in an hospital setting with high valuable animals (thoracic radiographs in adults, cardiac catheterism, angiography, magnetic resonance imaging). These ancillary tests have an interesting value in the diagnosis of the disease and therefore can have an impact on the therapeutic approach and the prognosis. The aim of this presentation is to make an up-to date review of the different ancillary tests that can be used in the diagnosis of cardiac and vascular diseases of cattle as well as their prognostic importance.
