Between supraventricular crest and pulmonary valve; comprised of the conus
arteriosus (infundibulum), ventricular septum and right ventricular free wall.
Carries blood out of the ventricle in an anterior-superior direction.
Importance in cardiovascular diseases:
The RVOT is an important anatomical feature in many corrective surgeries for
congenital heart defects and dilation of the RVOT can cause pulmonary valve
Importance in device delivery:
The anatomy of the RVOT is important in the delivery of transcatheter pulmonary
valve prostheses and surgical procedures regarding the pulmonary valve.
Additionally, in contrast to a septal placement, lead placement in the RVOT
typically results in the lead tip being implanted on the septal/free wall
margin or on the free wall itself.
