Unilateral absence of pulmonary artery with absent pulmonary valve in tetralogy of Fallot. (A) Outflow tract section showed the ventricular septal defect and aortic riding span. (B) Indistinct pulmonary valves, small development of the pulmonary annulus, significantly widened pulmonary artery and high-speed blood flow signal of two-way round trip in the spectrum Doppler. (C,D) Right subclavian artery was vagus, and the left pulmonary artery originated from the transverse arch of the aorta. (E,F) Anatomical casting showed that the absence of the pulmonary valve created a “whale’s tail” sign in the right pulmonary artery and that the left pulmonary artery originated from the transverse arch of the aorta. LV, left ventricle; RV, right ventricle; ARSA, aberrant right subclavian artery; LPV, left pulmonary vein; ARCH, aortic arch; DAO, descending aorta.
