ABSTRACT
Two foals with a history of normalcy at birth developed a lack of exercise tolerance and weakness in the first few days of life. Weakness, inability to rise, and reluctance to suckle were common complaints. Physical examination of both foals revealed a cardiovascular abnormality, with a loud systolic murmur audible over both thoracic walls. Additional diagnostic techniques were blood gas analysis, radiography, cardiovascular catheterization, and necropsy. Necropsy findings were ventricular septal defect, atrial septal defect, patent ductus arteriosus, and congenital absence of the aortic arch. Additionally, 1 foal had anomalous drainage of the cranial vena cava into the left atrium.

Three young unrelated dogs were diagnosed as having the canine counterpart of Ebstein's anomaly, an eponymic term for a cardiac malformation in man. All of the dogs had systolic murmurs in the tricuspid area, and all had radiographic evidence of cardiac enlargement, particularly of the right atrium. Electrocardiography indicated atrial disease or right atrial enlargement and right ventricular conduction defects. The defect was confirmed by means of cardiac catheterization in all 3 dogs. Open heart surgery was performed on 2 of the dogs--plastic reconstruction of the tricuspid annulus and placement of a prosthetic valve in 1 and closure of an atrial septal defect in the other; both of these dogs died (1 day and 1 month after surgery).

Four Collie littermates had multiple cardiac and diaphragmatic anomalies. Ventricular septal defect was found in 3, pulmonic stenosis in 2, atrial septal defect in 1, mitral regurgitaion in 1, and pericardial diaphragmatic hernia in 3. Five additional littermates died within 72 hours of birth but were not necropsied. On the basis of available evidence, it was believed that the defects were congenital but not hereditary.

A 2-year-old Brittany Spaniel ahd clinical signs of pulmonary diseases and pulmonary hypertension, with cardiac murmur and congestive heart failure. Aorticopulmonary septal defect was detected by means of cardiac catheterization. Attempted surgical correciton was unsuccessful.
