8 patients with atrial myxoma were reviewed. They ranged from 5 years to 55 years. Recently echocardiography has been the most helpful diagnostic procedure. Hemodynamically they simulated mitral valve disease with severe pulmonary hypertension. Tumour was demonstrated by angiocardiography. One of these tumours presented into the right atrium through an associated atrial septal defect. All of them underwent open heart surgery and removal of the tumour. One died as a result of septicemia. Others have had excellent hemodynamic improvement.
