Giant left atrial appendage aneurysm and atrial fibrillation: chicken or the egg?

Fetal atrial appendage aneurysm: Prenatal diagnosis by echocardiography and prognosis

“…The left atrial appendage aneurysm is more common than the right in the literature after birth, and the ratio of left to right atrial appendage aneurysm is ten to three. 1,8,12 However, the detection rates of the two groups were similar in our center, which was prominently different from children and adults. This difference may result from that children or adults having isolated atrial appendage aneurysm usually are asymptomatic and not detected in early life.…”

Blood Flow Dynamics in a Giant Left Atrial Appendage Aneurysm Visualized by 4D-Flow CMR

“…In this case report, we present the first known CMR 4D-flow analysis in a case of LAAA. LAAA is a rare entity, with mainly single case reports and 1 review of multiple case reports published ( 1 , 2 , 3 ). These aneurysms can be congenital or acquired, and acquired LAAA is mainly related to mitral valve disease.…”

A giant left atrial appendage aneurysm with recurrent chest tightness and atrial tachycardia: Multimodal imaging findings

“…Most LAAA's patients were initially asymptomatic, and several LAAA's were incidentally discovered by cardiac imaging. Those patients that were symptomatic had chest pain, palpitations, dyspnea, and thrombus embolism after middle age [2] , [3] , [4] . Given the potentially serious and life-threatening complications of LAAA, surgical resection has been proposed for most patients [5] .…”
