Fetal cardiac hemodynamics differ from those seen postnatally. During fetal life, blood is
oxygenated in the placenta and returns to the fetal body via the umbilical vein. Studies on …

A simple, reproducible, noninvasive Doppler index for the assessment of overall cardiac
function has been described previously. The purpose of this study was to correlate the …

The development of high-resolution ultrasound has allowed detailed examination of the fetal
heart. The accuracy of fetal echocardiography in the diagnosis of malformations of the fetal …

Physiological study of the developing mouse circulation has lagged behind advances in
molecular cardiology. Using an innovative high-frequency Doppler system, we …

Objective To determine whether heart failure is the mechanism underlying the association
between increased fetal nuchal translucency and congenital heart defects. Methods …

Objectives The pathophysiological background of an increased nuchal translucency (NT) is
still poorly understood. Cardiac dysfunction has been proposed as a cause. The aim of this …

Objectives Trisomy 21 is associated with an increased nuchal translucency thickness (NT),
abnormal ductus venosus (DV) flow at 11–14 weeks' gestation and congenital heart defects …

Abstract Knowledge of early developmental circulatory physiology has lagged behind
advances in molecular cardiology. Cardiovascular physiology changes during embryonic …

Understanding cardiac responses to exercise in healthy subjects is important in the
evaluation of youth with heart disease. This review article incorporates previously published …

Doppler assessment of left ventricular filling and ejection during dipyridamole stress may
supplement wall motion analysis for detection of myocardial ischemia and coronary artery …
