Abstract

We report a case of symptomatic and progressive enlargement of a huge left atrial appendage aneurysm in a 29-day-old infant. The aneurysm was detected by fetal echocardiography and exertional dyspnea developed during the neonatal period. The aneurysm was successfully resected by decompressing the aneurysm using cardiopulmonary bypass without cardiac arrest. Our findings suggest that fetal echocardiography enables early diagnosis of the rare left atrial appendage aneurysm, and early surgical resection may protect affected patients from life-threatening symptoms.

Cardiac Aneurysm

Aneurysm refers to a bulge of the wall or lining of a vessel commonly occurring in the blood vessels at the base of the septum or within the aorta. In the heart, it usually arises from a patch of weakened tissue in a ventricular wall, which swells into a bubble filled with blood. Discover the latest research on cardiac aneurysm here.
