Q. A 3000 g (6.6 Ib) male neonate is delivered full-term to a 35-year-old mother. The mother presented to the emergency department for crash delivery yesterday. The patient's past medical history is unknown. Upon examination, the neonate is distressed with working ala nasi. The respiratory rate is 75/min, and oxygen saturation is 85%. There is a noticeable blush discoloration over the neonate's hands, feet, and lips. Echocardiography reveals a small right ventricle with a regurgitant displaced tricuspid valve. Continuous shunting between the aortic arch and the pulmonary trunk is also noted. Further history of this patient will likely reveal?
