A 7-month-old girl is brought to the emergency room by her parents, who complain that their daughter is breathing rapidly and not taking feed. Physical examination reveals tachypnea, pallor, absent femoral pulses, and a murmur heard at the left axilla. A selective (differential) cyanosis of lower extremities is also noted. 2 weeks ago the infant underwent genetic analysis for a suspected chromosomal abnormality and results showed that chromosome X is entirely missing resulting in a 45 X karyotype. What is the likely cardiovascular abnormality expected in this patient?
