The inflow and outflow components of the RV are anatomically and embryologically distinct. The RVOT is tubular in shape and elevates the pulmonary valve above aortic valve. The chamber is thin walled, and twists around the aorta so that the pulmonary valve ends up to the left of the aortic valve. We are nearing the story of the “twist of the outflow tracts”
The “twist” in the story is long and complicated, with important implications in congenital heart disease – beyond the scope and need of this anatomy text. In the normal setting we make the following observations.
