Cardiac catheterization is rarely utilized to confirm the diagnosis of PPHN because echocardiography is diagnostic in excluding complex congenital heart disease and in evaluating the severity of pulmonary artery hypertension.  The risk/benefit ratio is also increased in this patient population when considering transportation of a sick newborn with PPHN to the catheterization laboratory and the possibility of precipitating a pulmonary hypertensive crisis during catheter manipulation.
