Aortic valvular dysplasia, a congenital abnormality not previously reported in cattle, was diagnosed in a 7-month-old Blonde d'Aquitaine heifer calf with a pulsating mass at the base of its neck, an enlarged area of cardiac dullness and a loud (grade IV/V) systolic cardiac murmur. Electrocardiography and thoracic radiography demonstrated that the left atrium and ventricle were enlarged. Dysplasia of 2 aortic valve cusps and post stenotic dilatation of the ascending aorta were identified by echocardiography and confirmed upon PM examination.
