Hannah's diagnosis of tetralogy of Fallot (a congenital heart defect)

When Hannah was 2 weeks and 4 days old she was diagnosed with tetralogy of Fallot. Tertalogy of Fallot (TOF) is a combination of four heart defects that are present together at birth, accounting for about 10% of all congenital heart disease.
The four defects that constitute the tetralogy of Fallot are:

  • Ventricular septal defect (VSD) -- A hole between the two bottom chambers, the ventricles, of the heart permitting oxygen-poor blood from the right ventricle to mix with oxygen-rich blood from the left ventricle.
  • Pulmonary stenosis -- Narrowing of the outlet to the pulmonary artery area with an abnormal Pulmonary valve impeding blood flow from the right ventricle to the lungs.
  • Right ventricular hypertrophy (RVH) -- Thickening and enlargement of the muscle of the right ventricle.
  • Overriding aorta -- The aorta overrides or straddles the wall (the septum) between the ventricles, permitting oxygen-poor blood to flow through the VSD into the aorta.
It was a very overwhelming and scary diagnosis. Jeff (Hannah's daddy) was at the police academy and I was staying with my parents until he graduated. I had alot of research to do in a short amount of time. I have learned alot!
Hannah was hospitalized in April for observation after having a few tet spells. Tet spells are when Hannah gets mad and turns blue. She had a tet spell after she got her shots at the doctors office. Tet spells are common and expected in children with TOF and indicate that it is time to repair the heart. We are so excited to get her heart fixed!!!
