A Misleading Left Atrial Appendage

Abstract

Left atrial appendage collapse is a relatively unusual echocardiographic finding. Although in post-cardiac surgery patients it may be an early sign of cardiac tamponade, and pericardiocentesis should be discussed, a conservative approach may be followed in cases secondary to viral infection without confusing it with a left atrial appendage thrombus. (Level of Difficulty: Intermediate.)
