Answer

Answer

The diagnosis of PPHN is confirmed by echocardiography. The cardinal findings include right ventricular dilatation, deviation of the interventricular septum, tricuspid regurgitation, and right-to-left shunting at the levels of the patent foramen ovale and patent ductus arteriosus. [5]
