Advances in echocardiography have enhanced our diagnostic imaging capabilities for congenital heart defects. In addition to improved resolution of two-dimensional images, cardiac hemodynamic assessment is possible with the use of Doppler, color Doppler, and stress echocardiography. Transesophageal echocardiography has allowed intraoperative assessment of cardiac repairs, and fetal echocardiography has allowed development of the field of fetal cardiology. The developing areas of intravascular ultrasonography and three-dimensional echocardiography show promise for the future. Echocardiography continues to revolutionize our ability to diagnose congenital heart defects accurately.
In conclusion, ventricular volume calculation from 2DE is feasible in the human fetus and improves the ability to calculate fetal ventricular size and ejection fraction. The right ventricle is clearly dominant at midgestation, but approaches left ventricular size at term. Calculation of the ventricular output from 2DE volume measurements is an accurate alternative to Doppler measurements.
