Double inlet left ventricle

Double inlet left ventricle

Overview

In double inlet left ventricle only the left lower heart chamber (left ventricle) is developed, and both upper chambers carry blood into this ventricle. A small, poorly developed right ventricle may be present. Double inlet left ventricle is one of several heart defects known as single (or common) ventricle defects, as there is essentially only one pumping chamber in the heart.
