A 5-month-old girl is brought to the emer- gency department by her parents because she is "turning blue." She is cyanotic, weak, and dyspneic. Her parents state that she has expe- rienced similar episodes in the past, but never this severe. Physical examination reveals the lungs are clear to auscultation, with no wheez- ing, rales, or rhonchi. Cardiac examination reveals a regular rate and rhythm, normal S1, single S2, a grade III rough systolic murmur at the left sternal border in the third intercos- tal space, and a palpable right ventricular lift. Echocardiography demonstrates unusual posi- tioning of the aorta, which overrides both the left and right ventricles in the long axis view. In this condition, the primary developmental defect occurs in which portion of the primitive heart? (A) Bulbus cordis (B) Conal septum (C) Left and right horns of the sinus venosus (D) Primitive atria (E) Primitive ventricle
