Radiologic patterns of the hypoplastic left heart syndrome.

The hypoplastic left heart syndrome is a malformative complex which unfortunately can not be treated surgically. This cardiopathy is the result of a serious embryogenic error and takes into consideration the different anatomic varieties described here. Borderline cases are also noted especially isthmic coarctation of the aorta or aortic stenosis in the neonatal period. Though several years ago, the diagnosis of the hypoplastic left heart syndrome was made only on pathology, it is now possible to make this diagnosis using clinical, laboratory and radiologic examinations. However, they are cases that remain difficult to label precisely, especially in minor forms and we feel that these deserve hemodynamic investigations.
