Isolated right atrial compression as a late sequela of aortic valve replacement.
Isolated right atrial compression occurred 31 months after aortic valve replacement. Aortic bleeding contained by adjacent pericardium produced a pseudoaneurysm and local atrial tamponade. Transthoracic echocardiography could not distinguish the extracardiac hematoma from an intra-atrial thrombus, temporarily misleading investigators.
