Abstract:
A 6-week-old Siberian Husky pup had an unusual group of congenital heart anomalies that included a right-to-left patent ductus arteriosus, a small left ventricular chamber and ascending aorta, and a dysplastic mitral valve that may have been stenotic. Anomalies were diagnosed, using cardiac catheterization, angiocardiography, and blood gas determinations. Findings were confirmed by postmortem examination.
