An 18-mo-old boy is brought to the pediatrician because of progressively worsening episodes of cyanosis. The child has moments where he turns blue and becomes dyspneic. During these episodes the child becomes irritable and remains in a squatting position. Physical examination reveals a small and thin child with clubbing of the fingers and toes. Lungs are normal. Heart auscultation reveals an RV lift and a grade III/VI harsh systolic ejection murmur at the upper left sternal border. Which of the following is the most likely diagnosis?

  1. Transposition of the great vessels (TOGV)

  2. Tetralogy of Fallot (TOF)

  3. Truncus arteriosus
