A Rare Case of Asymptomatic Giant Right Atrial Appendage Aneurysm

Right Atrial Appendage Aneurysm: A Systematic Review

“…2 RAAA thrombus was noted in 2 (11.76%) patients. The indications for surgery were increasing size (1) and recurrent atrial tachycardia even after ablation (1).…”

“…Asymptomatic patients were managed conservatively. 2 RAAA thrombus was noted in 2 (11.76%) patients. Three patients refused surgery and were treated medically with amiodarone for atrial tachyarrhythmia and anticoagulated for preven-tion of thromboembolism.…”

“…10 Risk factors associated with adverse outcomes including thromboembolic and arrhythmic complications included large RAAA size, large right atrial size, and associated congenital cardiac defects. 2,9 As there was no longitudinal follow-up with an outcome based endpoints, there is little supporting data for repeat imaging in these patients. 14 Symptomatic patients and those with enlarging aneurysm should undergo surgical resection (Fig.…”

“…15,16 A large or enlarging RAAA has been shown to be the predictor of thromboembolic complications or atrial arrhythmia. 2,9 As there was no longitudinal follow-up with an outcome based endpoints, there is little supporting data for repeat imaging in these patients. However, follow-up cardiac imaging (MRI) every 2 years has been suggested by some authors.…”

Use of cardiovascular magnetic resonance in the evaluation of a giant right atrial appendage aneurysm: a case report and review of the literature

“…As RAA aneurysms are often diagnosed in the context of atrial fibrillation, the development of intraluminal thrombosis and subsequent pulmonary or paradoxical systemic embolism is of concern [ 17 , 18 ]. Thrombus formation is as an indication in the literature for surgical resection of RAA aneurysms [ 17 , 18 ]. However, the differentiation of an intraluminal thrombus from flow stasis is not always straightforward, especially when using echocardiography and contrast-enhanced computed tomography (CT) alone.…”
