An unexpected left atrial mass was found during postoperative echocardiography in a 17-years old man following aortic valve replacement, suggesting thrombus, vegetation and neoplasm. Reoperation showed that the mass to be an inverted left atrial appendage. Left ventricular venting may cause such inversion. To prevent this complication, we suggest the use of careful monitoring and intraoperative transesophageal echocardiography.
