For proper diagnosis of<unk> , cardiac and non-cardiac features must be evaluated. Diagnostic criteria for atrial isomerism includes observation of symmetry of thoracic visceral organs upon echocardiogram, arrhythmia upon electrocardiogram, and chest x-ray for confirmation of the heart's location across the left-right axis. Additional radiographic and cross-sectional imaging may be obtained to evaluate both cardiac and non-cardiac manifestations of<unk> . In addition, a series of gastrointestinal tests can be conducted for observation of intestinal malrotation, as well as a scan of the liver and spleen for biliary function. Diagnostic techniques for cardiac causes * Echocardiography * Electrocardiography * Computed Tomography * Magnetic Resonance Imaging * Cardiac catheterization and angiography * Chest X-Ray Diagnostic techniques for non-cardiac causes * Computed Tomography * Magnetic Resonance Imaging * Splenic Function Analysis * Evaluation of Biliary Anatomy and Cholangiogram * Evaluation of Intestinal Malrotation * Pulse Oximetry Other diagnostic features * Assessment of Family History * Genetic Testing
