Abstract
A Bulldog puppy that died at 1 day of age was presented for postmortem evaluation. Macroscopically, there was marked hypoplasia of the ascending, transverse, and proximal segments of the descending thoracic aorta and almost complete secondary thrombosis of the left ventricle causing a functional stenosis of the left atrioventricular valve. Separately, there was right atrioventricular valve dysplasia with secondary dilation of the right atrium. Microscopically, the left ventricular outflow tract was occluded by chondroid metaplasia, fibrosing recanalization of a left ventricular thrombus, and isolated Purkinje fiber degeneration and necrosis.
