The normal ductus arteriosus (arrowed) of a 2nd trimester fetus is seen well in
this gif video. Sp= spine, rv= Right ventricle, Rt= right side of the
fetus, Lt= left side of fetus, Ao= aorta

In these images (above) the ductus arteriosus is marked by an asterix.
Ultrasound image of the Right Ventricular Outflow Tract (RVOT):
Ultrasound image shows the RVOT, the pulmonary trunk and bifurcation into the
right and left pulmonary arteries. Image courtesy of Dr. Gunjan Puri, India.
Ultrasound images of the LVOT (Left Ventricular Outflow Tract):
These 2 sonographic images of the fetal heart show the Left ventricular outflow
tract as it leaves the left ventricle. LV= left ventricle; RV= right ventricle.
Some more images of LVOT and RVOT:
The above ultrasound images of the fetal heart (fetal echocardiography) show the
left ventricle (image on right) with the left ventricular outflow tract emerging
from it to enter the aortic arch. The image on left shows the right ventricular
outflow tract (RVOT) with the pulmonary trunk emerging from the right ventricle.
This is seen to divide into the right and left pulmonary arteries. Ultrasound

Four Chamber view:
This sonographic image shows the normal four chambers of the fetal heart.
