In brief: A congenital defect

Hypoplastic left heart syndrome (hlhs) is a specific type of congenital heart defect that consists of varying degrees of underdevelopment of the left-sided heart structures including the mitral valve, left ventricle, aortic valve, and aortic arch.
Hlhs most likely has a genetic cause and occurs early during fetal development, however the genes involved have not yet been entirely elucidated.
