Reyes CV et al has reported 38 cases [2]. They noted that it is more likely in seventh and eighth decades of life.<\/p>\n<p>Heyer CM et al picked up 28 cases from 1292 patients who underwent multi-slice computerized tomography (MSCT) of thorax [3]. The mean age of affected patients in this series was 72.2 years. MSCT also showed the dumb bell shape in all patients with sparing of the fossa ovalis region. Atrial septal thickness ranged from 20 mm to 62 mm and craniocaudal extent ranged from 51 mm to 89 mm. Advanced age, obesity and atrial arrhythmia were associations. One patient had hemodynamic obstruction.<\/p>\n<p><strong><span style=\"color: #0000ff;\">Reference<\/span><\/strong><\/p>\n<ol>\n<li>Maleszewski JJ, Bois MC, Bois JP, Young PM, Stulak JM, Klarich KW. <a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/29976295\/\">Neoplasia and the Heart: Pathological Review of Effects With Clinical and Radiological Correlation<\/a>.
