OBJECTIVES The purpose of the study was to determine the accuracy of the prenatal echocardiographic diagnosis and prognosis of fetuses with conotruncal anomalies. BACKGROUND The accuracy of prenatal echocardiographic diagnoses of cardiac lesions has been reported, but no previous reports specifically address fetal conotruncal anomalies. METHODS Medical records of 61 fetuses, in which a feta...
Conotruncal and ventricular septal congenital heart anomalies result from defects in formation and division of the embryonic outflow tract. Cardiac remodeling during outflow tract and ventricular septation converts the tubular embryonic heart into a parallel circulatory system with an independent left ventricular outlet and right ventricular inlet. Tbx3 encodes a T-box-containing transcription ...
BACKGROUND CHARGE syndrome is a complex multiple congenital malformation disorder with variable expression that is caused by mutations in the CHD7 gene. Variable heart defects occur in 74% of patients with a CHD7 mutation, with an overrepresentation of atrioventricular septal defects and conotruncal defects - including arch vessel anomalies. METHODS AND RESULTS We report an index patient with...
Heart defects are among the most common congenital anomalies, occurring in approximately 1% of newborn populations. Conotruncal heart defects (CTHD), which account for 50-60% of all congenital heart malformations, are known to have a strong genetic component. They occur either as an isolated malformation or in association with extracardiac anomalies. In particular, CTHD constitute a cardinal co...
We used non-invasive high frequency ultrasound to screen N-ethyl-N-nitrosourea mutagenized mouse fetuses for congenital cardiovascular anomalies. We ultrasound scanned 7546 mouse fetuses from 262 mutagenized families, and identified 124 families with cardiovascular defects. Represented were most of the major congenital cardiovascular anomalies seen clinically. The ENU-induced mutations in sever...
