Abstract

When a new left atrial mass is discovered by means of echocardiography, the differential diagnosis is usually
between thrombus, vegetation, and tumor. In the past decade, however, the physicians were able to document
another cause. Our aim is to introduce a case of postoperative inverted left atrial appendage which caused left
ventricular inflow obstruction requiring reoperation. We report a 4- year old boy who had inverted left atrial appendage
after atrial septal defect repair. He showed signs and symptoms of pulmonary edema postoperatively.
We assessed him by echocardiography and discovered a mass in his left atrium necessitating re-operation. The
surgeon found and restored inverted left atrial appendage intra-operatively. Because inverted left atrial appendage
can cause severe and occasionally life threatening complications, we believe intraoperative transesophageal
echocardiography is highly essential to diagnose this pathology and to avoid restorative reoperation.
