Hypoplastic Left Heart Syndrome (HLHS)

Hypoplastic Left Heart Syndrome: “Hypoplasia” is a term, which means something is made small. Therefore, in this defects the left ventricle fails to develop normally. As the left ventricle (LV) is the “workhorse” of the heart, patients with this syndrome are not able to live to long without surgical attention. Once again, the severity of the defect depends in how small the left ventricle, mitral valve and aorta (AO) are, how much flow goes through the left heart, and how big the holes are within the heart.
