Absence of the aortic valve: antenatal and postnatal two-dimensional and Doppler echocardiographic features

Journal of the American College of Cardiology
F Z BiermanH Fox


Antenatal and postnatal two-dimensional and gated pulsed Doppler echocardiography, beginning at 32 weeks' gestation, were used to evaluate the cardiovascular contribution to nonimmunologic hydrops in a gravida 1, para 0 nineteen year old woman. Antenatal two-dimensional imaging demonstrated a hypoplastic left heart variant of complete common atrioventricular (AV) canal. Antenatal gated pulsed Doppler examination of the fetal thoracoabdominal aorta revealed atypical pandiastolic retrograde flow. Postnatal noninvasive examination at 36 weeks' gestational age was unchanged from the prenatal study. Postmortem examination confirmed the noninvasive anatomic findings and revealed polysplenia. The mechanism of pandiastolic retrograde flow was attributable to "absence of the aortic valve," a previously unreported congenital cardiac anomaly, which resulted in severe antenatal and postnatal aortic regurgitation.

Birth Defects

Birth defects encompass structural and functional alterations that occur during embryonic or fetal development and are present since birth. The cause may be genetic, environmental or unknown and can result in physical and/or mental impairment. Here is the latest research on birth defects.
