Neonate 2 days of life, transthoracic echocardiogram, parasternal short-axis view. (A) Two-dimensional echocardiogram demonstrates a small thrombus (arrow) in the narrowed pulmonary ductus segment, on the left of the left pulmonary artery. (B) In color-flow Doppler a left-to-right shunt through the ductus was detected, from the aorta to the pulmonary artery.
