  • COMMENTS:
    • While it is difficult to show off all the lesions of Tetralogy of Fallot in a single cut, this particular section demonstrates very nicely the overriding aorta (which receives blood from both the left and right ventricle), whose major result in hypoxemia of the individual. You can also see marked right ventricular hypertrophy. Not evident is a ventricular septal defect or pulmonic stenosis. There also appears to be right atrial dilation (the result of volume overload).
