title: [Aneurysms of the interauricular septum. Review of the literature apropos of 8 cases].
abstract: The authors present 8 cases of aneurysms of the interauricular septum (AIAS). The diagnosis was established in all cases by two-dimensional echocardiography (E2D) which was requested, three times following a cerebral vascular accident (CVA). The AIAS manifest themselves as localised "hernias" of the inter-auricular septum, mobile during the cardiac cycle. Their topography was strictly right inter-auricular in 6 cases, whereas in the other 2 patients the AIAS passed into the left atrium at protosystole and returned to the right atrium at telesystole. Catheterization with angiography was carried out 5 times: the inter-auricular septum was crossed 4 times without gasometric reasons for an associated shunt; the AIAS was opacified in all cases. An anti-coagulant treatment was prescribed for 3 patients who had suffered a CVA, and for a fourth presenting numerous supraventricular extrasystoles which were sometimes grouped. A review of the literature of the last fifty years enabled a compilation of 93 cases of AIAS to be made, 49 of which had been examined by E2D, 35 had had a hemodynamic and angiographic exploration and 47 an anatomical and/or surgical confirmation. The main results obtained are described and commented on. The diagnostic, etiopathological and prognostic problems raised by the "updating" of this pathology are discussed.
