Abstract
BACKGROUND Congenital atrial appendage aneurysm (AAA) is a rare malformation which can coexist with potentially lethal complications. We aimed to summary echocardiographic characteristics and prognosis of fetal AAA. METHODS We retrospectively analyzed the echocardiographic data of 17 fetuses with AAA,and their outcomes or pathological reports were also collected. RESULTS Eight fetuses with left AAA (LAAA) and 9 fetuses with right AAA (RAAA) were identified. Five fetuses were diagnosed with other cardiac defects. Two fetuses with RAAA presented with arrhythmias, including atrial premature beats (n = 1) and bradyarrhythmia (n = 1). LAAA could be detected by four-chamber view (50.0%) and short-axis view (100.0%). RAAA could be detected by four-chamber view (100.0%), and view of right ventricular inflow tract (33.3%). There were three cases with mild pericardial effusion. Three cases with complex cardiac defects were selectively terminated, with confirmation of LAAA by autopsy in one case. Fourteen fetuses were born. After following 2 (range, 1-5) years, the AAA disappeared in one case with LAAA and two cases with RAAA. While, 11 cases were still diagnosed with AAA. Atrial premature beats with RAAA, which appeared in prenatal period, still persisted after birth. CONCLUSION Congenital AAA is a rare abnormality in utero. The short-axis view and the four-chamber view were the most useful views to detect fetal AAA. Fetal AAA may disappear in childhood. Atrial tachyarrhythmias in utero may exist persistently after birth. Patients with AAA should be followed up closely and appropriate intervention should be taken when complications appeared.

Abstract
BACKGROUND Aneurysm of the left atrial appendage is rare. We sought to systematically review the published literature on left atrial appendage aneurysm (LAAA) to address its demographic features, clinical characteristics, treatment, complications, and outcomes. METHODOLOGY A systematic electronic search of Medline, PubMed, and EMBASE for case reports, case series, and related articles of LAAA published from 1962 until July 2013 was carried out. Statistical analysis was done using SPSS version 20.0. Logistic Regression Analysis was used to identify the independent predictors of LAAA-related thrombus formation and embolism. RESULTS Eighty-two cases of LAAA were identified. There was a slight female preponderance and most of the patients presented in their third decades. Palpitation, dyspnea or both were most common clinical symptoms associated with LAAA. Echocardiography was the main diagnostic modality used and the mean size of aneurysm was 7.08 ± 3.03 × 5.75 ± 2.36 cm. Surgical resection of the aneurysm was performed in most patients with favorable results. Systemic embolism and atrial tachyarrhythmias were the two common complications associated with untreated LAAA. Presence of atrial fibrillation/flutter was the only significant predictor of thrombus formation/embolic events. CONCLUSION Aneurysm of left atrial appendage is rare and often an incidental diagnosis during echocardiography. It is important to recognize this entity since it is associated with cardiovascular morbidity and mortality by predisposing to atrial tachyarrhythmia and thromboembolism. Surgical resection is the standard of treatment in the current literature. Medical management is directed toward the treatment of thromboembolism and atrial tachyarrhythmia.

Abstract
Aneurysm of the left atrial appendage is an extremely rare anomaly. We describe the case of a 68-year-old man who presented with palpitation and was found to have a very large aneurysm located near the left atrial appendage on routine echocardiography. During surgery, an additional small aneurysm of the right atrial appendage was found. Both atrial aneurysms were resected in addition to mitral annuloplasty and a maze procedure.
