Tetralogy of Fallot

  • four features

    • 1 VSD

    • 2 subpulmonic or pulmonary valve stenosis

    • 3 aortic valve overrides VSD

    • 4 right ventricular hypertrophy

  • clinical severity depends on severity of pulmonic stenosis and size of VSD

diagram of tetralogy of Fallot

  • VSD is present

  • aortic valve overrides the VSD

  • right ventricle pumps blood into left ventricle as well as directly into the aorta

  • this leads to deoxygenated systemic circulation and cyanosis

gross specimen

  • aorta is huge, pulmonary artery is small

  • here the stenosis is not horrendously severe because the ratio of aortic:pulmonic flow might be 2:1

  • in any case, right ventricle is very hypertrophic

gross specimen

  • pulmonary artery is much smaller than aorta
