This report describes the ability of computed tomography angiography (CTA) imaging of the heart to visualize an acquired shunt between the left ventricular outflow tract (LVOT) and the right atrium (RA) (Gerbode defect). Previously, transesophageal echocardiography (TEE) has been the mainstay of diagnosis. To the best of our knowledge, the use of cardiac CTA imaging to visualize and diagnose this disorder has not been previously reported. Cardiac CTA allows for more detailed visualization of cardiac anatomy and can supplement or supplant TEE as the diagnostic test of choice for evaluation of patients with this rare defect.
