This animation is part of the problem-based learning case “Tin Man” in the veterinary curriculum of the College of Veterinary Medicine at Western University of Health Sciences. Tin Man was a 4-month old domestic short-hair cat from a local shelter presented with a VI/VI right-sided systolic murmur. This animation shows the four major defects that characterize Tetralogy of Fallot: ventricular septal defect (in dark blue), pulmonic stenosis (in light blue), the dextroposition of the aorta (green string), and the hypertrophy of the right ventricle. This animation was designed to help students interpret the images and identify the abnormalities.
