Giant Left Atrial Appendage Aneurysm: Surgical Treatment to Prevent Potential Complications.

Left atrial appendage aneurysm (LAAA) is a rare anomaly, which predisposes to hazardous cardiovascular events. We present a rare case of a 26-year-old female with a giant left atrial appendage aneurysm. The left atrial appendage was incidentally detected during her pregnancy. Six months later after her parturition, the patient was referred to our department and successfully received surgical treatment prophylactically to prevent potential complications. To the best of our knowledge, only about 100 cases of LAAA have been reported.
