  •  disorder in which the entire left side of the heart is underdeveloped
  •  the right side of the heart is dilated and hypertrophied, and supports both the systemic and pulmonary circulations via PDA
  •  accounts for nearly 1/4 of all cardiac deaths in the first year of life
  •  infants present within the first days or weeks of life acutely ill with signs of CHF
  • PE often shows cyanosis and poor pulses but hyperdynamic cardiac impulses
  • CXR shows cardiac enlargement and prominent pulmonary vasculature
  • EKG shows RA and RV hypertrophy
  • echo is diagnostic
  • acute treatment is PGE1 to maintain the PDA.
