We studied seven hearts with abnormalities of the atrial septum or the mitral valve. Three had abnormalities of the atrial septum, characterized by a flap or a diaphragm within the left atrium. Another three cases had abnormal cords extending from the atrial septum to the anterior or the posterior mitral leaflets. A seventh case had a duplicated mitral valve. Grossly, the specific conditions among these seven hearts appeared very different; however, we believe that the origin of each anomaly can be explained by one of three developmental aberrations or a combination hereof. Although only one case was associated with severe cardiac disease, such structures may be seen during cardiac imaging or operation.
