Composite illustration of PPHN as found in our patient. (A) reversed flow in the aortic arch due to right-left shunt over the ductus arteriosus; (B) D-shaped left ventricle (LV) due to elevated right ventricle (RV) pressure; (C) peaked flow signal in main pulmonary artery (MPA) as commonly seen in pulmonary hypertension; (D) tricuspid regurgitation with systemic level pressure gradient indicative of pulmonary hypertension.

The left ventricular function was adequate, and the contractility of the right anterior wall was decreased (Fig. 1).
