“…These aneurysms predispose the patient to AF because of the ectopic foci of atrial rhythm generation and thrombus formation because of sluggish blood flow, which may lead to lifethreatening systemic emboli [1]. Because of these major complications, early diagnosis and surgical excision are mandatory even in asymptomatic, otherwise healthy patients [1,2]. Median sternotomy aided by CPB is the most common approach and is considered Fig.…”

“…Dilatation of the left atrium (LA) and the left atrial appendage (LAA) can be congenital or acquired. Acquired cases are generally secondary to mitral valve disease, left ventricular dysfunction, or other conditions that lead to elevated atrial pressure [1]. However, true congenital aneurysms most frequently involve the atrial appendage but may extremely, rarely arise from the body of the LA [2].…”

Background Congenital left atrium (LA) aneurysms are extremely rare entities in clinical practice and most frequently involve the atrial appendage and rarely arise from the body of LA, We report a case of giant LA aneurysm compressing heart and presenting in a very late stage. Case summary A 31-year-old male, who was diagnosed to have dextrocardia, rheumatic heart disease, and atrial fibrillation and was kept on medical treatment long time ago, presented with congestive heart failure symptoms and cardiogenic shock. Emergency transthoracic echocardiography was done revealing situs solitus with aneurysmally dilated LA pushing heart to the right side (dextro-posed heart), moderate mitral regurgitation, and severe pulmonary hypertension, however, pulmonary artery anatomy could not be properly visualized so computed tomography (CT) was preformed confirming diagnosis and revealing compressed pulmonary arterial tree by the dilated LA, unfortunately patient died before proceeding to surgical intervention. Discussion Congenital left atrial aneurysms are extremely rare anomaly and may be associated with significant morbidity. And, therefore, should be remembered as a potential anatomic cause of atrial arrhythmias or embolic phenomena, or both. The diagnosis may be easily established through non-invasive complementary techniques, such as echocardiography, CT, and cardiac magnetic resonance imaging. Symptomatic patients, those with large aneurysm or compelling indications for surgery should undergo surgical resection.

Introduction The left atrial appendage (LAA) is a distinct structure with unique developmental and structural characteristics. The LAA is involved in the formation of intra-atrial thrombi, particularly in patients with conditions such as atrial fibrillation and mitral valve disease. Left atrial appendage aneurysms (LAAA) are rare abnormal dilations of the LAA that may cause hazardous complications. However, there are limited data on the demographic features, clinical characteristics, management modalities, and prognosis of LAAA patients. This study aimed to conduct a systematic review of the reported cases of LAAA to explore the baseline characteristics, presentation, preferred diagnostic modalities, and optimal management of LAAA. Methods A systematic review was conducted following the PRISMA guidelines. We performed a literature search using MEDLINE/PubMed and Google Scholar. Eligible articles published between January 1940 and November 2022 were included. The eligibility criteria included case reports and case series of LAAA in English language articles. The data extracted included information on the authors, publication year, patient characteristics, signs/symptoms, diagnostic procedures, treatments, and outcomes. Results We identified 177 patients with LAAA in our study. There was a slight female predominance (50.9%), and the mean age was 29.7 years. Palpitations were the most common symptom reported, followed by shortness of breath and thromboembolic events. Transthoracic and transesophageal echocardiograms were the most common modalities for investigating and diagnosing LAAA, and the mean size of the aneurysm was 7.8 (5.7–9.6) × 5.9 (5.0-6.2) cm. Surgical resection is the treatment of choice for most patients with excellent prognoses. Older age and the presence of arrhythmia were significantly associated with thrombus formation and embolic events. Conclusion Left atrial appendage aneurysm is a rare but potentially life-threatening heart pathology that can lead to arrhythmias and thromboembolic events. Surgical resection appears to be the primary treatment option in the current literature, and most patients show improvement or are asymptomatic after treatment. Additionally, alternative approaches, such as transcatheter closure of LAAA, ablation, and medical treatments, have been reported as viable alternatives to surgical intervention.
