PY - 2018 T2 - Practical Neonatal Echocardiography AB - A patent foramen ovale, patent ductus arteriosus, and patent ductus venosus are the three vital fetal channels that ensure a normal fetal circulation. Right-to-left shunting through the foramen ovale significantly contributes to the output of the left ventricle, which functions in parallel with the right ventricle to ensure normal fetal cardiac output. This chapter focuses on the important role of the patent foramen ovale in the fetus, and its function and impact in postnatal life. Of note, this chapter will not address other types of atrial defects producing interatrial shunting in neonates with congenital heart disease. This topic will be addressed in Chapter 15.
