    Abstract:
    To investigate the normal configuration of the tricuspid valve and the normal size of the tricuspid valve ring, 17 normals, 20 patients with atrial septal defect, 4 patients with tricuspid valve prolapse, and 41 patients with various diseased conditions were studied by cross-sectional echocardiography. The tricuspid valve ring diameter in atrial septal defect was judged to be increased in comparison with that of normals. All the patients with tricuspid valve prolapse exhibited an excessive systolic ballooning of the leaflets toward the right atrium. However, a systolic ballooning of the leaflets alone was frequently observed in normals and many other conditions. Therefore, we conclude that cross-sectional echocardiography has some clinical limitations in the differential diagnosis between tricuspid valve prolapse and normals.
