Prichard's structures of the fossa ovalis are age-related phenomena composed of nonreplicating endothelial cells: the cardiac equivalent of cutaneous senile angioma.


Prichard's structures or minute endocardial deformities with lacunas of capillary size lined by plump endothelial cells located in the fossa ovalis are an age-related alteration of unknown origin.
