title: Idiopathic dilation of the right atrium: case report and survey of the literature.
abstract: Idiopathic dilation of the right atrium (IDRA) is a rare cardiac anomaly of unknown etiology. Whether it is an acquired or congenital lesion is controversial. A case of IDRA detected in utero and confirmed postnatally is reported. The postnatal course was complicated by the development of atrial flutter successfully treated with sotalol. A review of the literature concerning IDRA is presented.
