Key result
Surgical resection of a giant LAA aneurysm compressing the LAD improves LV systolic function.
Why the study?
Left atrial appendage aneurysm is a rare congenital heart disease with limited data on its diagnosis and effects on surrounding structures.
Case Report (n=1)
Surgical resection of a giant left atrial appendage aneurysm compressing the left anterior descending coronary artery can lead to recovery of impaired left ventricular systolic function.
May support resection for rare giant LAA aneurysms with LAD compression; leaves open generalizability beyond this single pediatric case.
Left atrial appendage aneurysm (LAAA) is a rare congenital structural heart disease. It is often diagnosed by echocardiography; however, other imaging modalities can add to its diagnosis and its potential effects on the surrounding structures. A 16-year-old boy presented with dyspnea and palpitation. Transthoracic echocardiography showed a large LAAA communicating with the LA through a narrow neck with impaired left ventricular (LV) systolic function. Multidetector cardiac tomography showed that the LAAA is compressing the left anterior descending artery. The LAAA was surgically resected followed by improvement of the LV systolic function.

Wagdy et al. (2016) conducted a case report in Left atrial appendage aneurysm (n=1). Surgical resection was evaluated on Improvement of LV systolic function. Surgical resection of a giant left atrial appendage aneurysm compressing the left anterior descending artery in a 16-year-old boy led to improvement of left ventricular systolic function.
