Double Inlet Left Ventricle
Double Inlet Left Ventricle Diagram
The Double Inlet Left Ventricle diagram (DILV) at left illustrates the anatomical complications present in most forms of this congential heart defect.

1. Small right ventricle on left side of the body.
2. Ventricular septal defect (VSD)
3. Transposition of the great arteries (pulmonary artery and aorta)
4. Double inlet left ventricle, both the mitral and tricuspid valve open into the enlarged left ventricle
5. Atrial septal defect (ASD)
6. Ventricular inversion (position of ventricles reversed from normal)
7. Left aortic arch

Double Inlet Left Ventricle is one of the so-called Single Ventricle heart defects, as there is effectively only one pumping chamber in the heart.
