Heart and Blood Conditions
Double Inlet Left Ventricle
What is double inlet left ventricle?
Double inlet left ventricle is a rare birth defect in which the
both lead into the left
. These valves act as doors, letting blood flow from the
to the ventricle.
Normally, the tricuspid valve leads into the right ventricle, and the mitral valve leads into the left ventricle. A wall called the septum separates the two ventricles.
With this defect, both valves let blood flow into the left ventricle, and only the left ventricle works. Because the right ventricle is not being used, it is small and not well developed.
This is also called a single-ventricle heart defect because children with this defect have only one pumping chamber in their heart that works. Single-ventricle defects are some of the most complex heart birth defects.
Double Inlet Left Ventricle in Children
This is a
defect. Doctors do not know why it happens. They think it occurs early in the pregnancy, when the baby's heart is forming.
About five in every 100,000 babies have double inlet left ventricle.
Children with this defect may have other heart problems, too, like
transposition of the great arteries
coarctation of the aorta
