Key result
Echocardiography identifies inverted left atrial appendage masquerading as a postoperative left atrial mass.
Why the study?
An inverted left atrial appendage is a rare postoperative lesion that can mimic a cardiac mass and lead to unnecessary diagnostic procedures.
Case Report (n=1)
Echocardiography may identify inverted LAA among post-operative left atrial masses; leaves open its reliability versus multimodality imaging in broader cohorts.
An inverted left atrial appendage is a rare phenomenon post cardiac surgery. The lesion presents as an additional mass in the left atrium, which would trigger unnecessary concerns and frequently, a battery of tests. The lesion can be easily diagnosed using echocardiography. We report a case of inverted left atrial appendage in a patient post repair of common arterial trunk. Echocardiographic pictures and features which help to identify this lesion as well as to differentiate it from other possible left atrial mass are described. This article aimed to improve the awareness of sonographers toward this rare but possible post operative lesion.

Leong et al. (2012) conducted a case report in Inverted left atrial appendage post cardiac surgery (n=1). Echocardiography was evaluated. Echocardiography can successfully diagnose an inverted left atrial appendage, a rare post-operative lesion masquerading as a cardiac mass, differentiating it from other left atrial masses.
