Cardiac outflow tract
WebThe RVOT is an important anatomical feature in many corrective surgeries for congenital heart defects and dilation of the RVOT can cause pulmonary valve insufficiency. The anatomy of the RVOT is important in the delivery of transcatheter pulmonary valve prostheses and surgical procedures regarding the pulmonary valve. WebThe left ventricular outflow tract in the fetal heart is seen by obtaining a long-axis view of the heart. The scan head is angled slightly anteriorly and medially (right) from the aortic root. The right ventricle is anterior to the left ventricle. The normal aorta is about 3 mm at 20 weeks. The number of cusps of the aorta should be noted.
