Prenatal diagnosis of congenital absence of aortic valve associated with restrictive foramen ovale: Hemodynamic features and clinical outcome

J Clin Ultrasound. 2019 Feb;47(2):104-106. doi: 10.1002/jcu.22636. Epub 2018 Oct 14.

Abstract

We present the case of a fetus with absent aortic valve (AAV), mitral regurgitation (MR), and restrictive foramen ovale (FO) who survived in utero but died of severe hypoxia after birth. We reported previously two cases of "inverse circulatory shunt" in AAV with MR, that is, blood from the ascending aorta flowing into the left ventricle through aortic regurgitation, to the left atrium due to MR, to the right atrium through FO, to the right ventricle, then to the pulmonary arteries, and to the ascending aorta through the ductus. In the present case, restrictive FO prevented inverse circulatory shunt, but resulted in postnatal death.

Keywords: absent aortic valve; inverse circulatory shunt; restrictive foramen ovale.
