title: [Endocardial cushion defects  in situs solitus and in asplenic and polysplenic syndromes, Anatomoembryological correlations].
abstract: The endocardial cushion defects were studied in hearts belonging to situs solitus and in the asplenia and polysplenia syndroms. WE propose that these defects must be classified by identifying persistent developmental stages. Such classification would content the anatomical varieties seen in the asplenia and polysplenia syndroms. The embryological bases are discussed.
