Atrial Septal Aneurysm Associated With Systemic Embolism and Interatrial Right-to-Left Shunt

Arch Intern Med. 1987;147(3):605-606. doi:10.1001/archinte.1987.00370030203043

• Prior to the advent of two-dimensional echocardiography, atrial septal aneurysm was rarely diagnosed during life. In this article, two-dimensional echocardiography identified an atrial septal aneurysm as the site of intracardiac right-to-left shunting, causing hypoxemia in a patient with acute right ventricular infarction. In addition to this rare presentation, the patient also had systemic embolism, a known complication of atrial septal aneurysms.
