Right Atrial Appendage Aneurysm: A Systematic Review

Abstract

Right atrial appendage aneurysm although rare may be associated with significant morbidity. Surgical resection is indicated in symptomatic patients.

Neonatal Management of a Giant Right Atrial Appendage Aneurysm

“…A recent review identified just 17 cases reported in the literature to date, with only 3 cases identified in neonates. 1 These aneurysms can be associated with tachyarrhythmia, intracardiac thrombus formation, thromboembolism, and right ventricular compression precipitating heart failure. 1,2 In some instances, enlargement of the appendage may be related to idiopathic dilation of the entire right atrium, an entity that has been associated with sudden death.…”

A Rare Case of Asymptomatic Giant Right Atrial Aneurysm: Case Report

“…Correct diagnosis is necessary for planning therapy. 10 The diagnosis of right atrial aneurysm can be established with echocardiography, angiography, CT, or MRI. In our case, right atrial aneurysm was diagnosed by echocardiography, TEE, and confirmed by CT angiography.…”

Giant Right Atrial Aneurysm ― Multimodality Imaging ―

“…He had no cardiac symptoms and physical exami- arrhythmic complications. 6 The common arrhythmias are supraventricular arrhythmias such as AF. 7 While symptomatic patients and those with an enlarging aneurysm should undergo surgical resection, a conservative approach has been recommended for asymptomatic patients.…”

“…7 While symptomatic patients and those with an enlarging aneurysm should undergo surgical resection, a conservative approach has been recommended for asymptomatic patients. 6 Asymptomatic patients managed conservatively should receive anticoagulation for the prevention of thrombus formation. Because the present patient was asymptomatic but had a large aneurysm with a whirling blood flow and LGE of the atrial myocardium, treatment consisted of anticoagulation and conservative management with annual imaging surveillance.…”
