Aortopulmonary window, left coronary artery aneurysm, and redundant aortic valve leaflet in a calf: the use of multimodal imaging to diagnose congenital heart disease

A 2-month-old male Holstein calf was presented for evaluation of a continuous systolic murmur. A grade V/VI left basilar continuous murmur and a grade IV/VI right basilar continuous murmur was auscultated upon evaluation with increased respiratory effort, wheezes, and crackles. Multimodality diagnos...

Summary:A 2-month-old male Holstein calf was presented for evaluation of a continuous systolic murmur. A grade V/VI left basilar continuous murmur and a grade IV/VI right basilar continuous murmur was auscultated upon evaluation with increased respiratory effort, wheezes, and crackles. Multimodality diagnostics were performed on this patient for further workup and included transthoracic and transesophageal echocardiography, fluoroscopy guided angiography, and gross necropsy with histopathology. An aortopulmonary window with continuous left-to-right shunting was identified at the level of the left aortic sinus of Valsalva with a severely dilated left coronary artery and left-sided congestive heart failure. This case report outlines the diagnostic workup of a rare congenital heart defect and secondary cardiac abnormalities not previously identified in veterinary literature.
