An inverted left atrial appendage-when it gives a surprise on the table

A newly identified left atrial (LA) mass on a post-repair intraoperative transoesphageal echocardiogram (TEE), following a left ventricle (LV) thrombectomy, will make the surgical team wonder-whether a part of the thrombus has been dislodged into the LA or what else could it be? This report is about a 34-year-old male who underwent LV thrombectomy, for whom the post cardiopulmonary bypass intra-operative TEE showed a new LA mass that turned out to be an inverted left atrial appendage on exploration.
