“…In the congenital form, the formation of the aneurysm occurs due to dysplasia of the scallop muscles and associated atrial muscle fibers[ 5 ]. Poor contractile function leads to a gradual expansion and extension of the left atrial appendage as a result of increased internal pressure[ 7 ].…”

BACKGROUND An aneurysm of the left atrial appendage is one of the rare but potentially hazardous heart defects. The risk of lethal complications grows with its size. To date, about 150 cases of this defect have been described in the literature. We present a case of left atrial appendage aneurysm with the deformation of the mitral valve and the left main coronary and circumflex artery, which required mitral valve annuloplasty and bifurcation stenting. CASE SUMMARY A 58-year-old man presented to our hospital complaining of shortness of breath, general weakness, dizziness during physical exertion, and fatigue. Based on the results of echocardiography, an aneurysm of the left atrium was suspected. A free-breathing real-time cine magnetic resonance imaging with electrocardiograph synchronization confirmed the diagnosis of left atrial appendage aneurysm. The patient underwent an aneurysmectomy via a median sternotomy with cardiopulmonary bypass. Intraoperative transesophageal echocardiography revealed relative mitral insufficiency that was corrected with an annuloplasty ring. Intraoperative coronary angiogram showed impaired blood flow in the left main coronary and circumflex artery and 60% stenosis. For this reason, bifurcation stenting was performed. The patient had an uneventful postoperative clinical course and was discharged from the hospital on the 10th day in a satisfactory condition. CONCLUSION Left atrial appendage aneurysm is a rare and dangerous heart pathology that requires surgery to prevent related complications.

“…Therefore, when the diagnosis is confirmed, surgical resection is generally recommended. 12,13 Our patient refused surgical treatment despite the risk of thromboembolism and rupture. As such, we recommended the clinical administration of drug thrombolysis and regular follow-up.…”

Congenital left atrial appendage aneurysm is an extremely rare heart malformation. Some researchers also call it left atrial appendage diverticulum. Here, we report a patient who was hospitalized due to paroxysmal palpitations that became worse for 2 months. Transthoracic echocardiography and contrast echocardiography suggest a left atrial appendage aneurysm with thrombosis. Magnetic resonance imaging showed long T2 and slightly short T1 signal at the top of the left atrial appendage aneurysm. Computed tomography examination showed that the left atrium was connected to the giant left atrial appendage. The patient refused surgery despite the high risk of thromboembolism. Key words: left atrial appendage aneurysm, congenital heart malformation, thrombus

“…Left atrial appendage aneurysm is a rare abnormality characterized by either local or diffuse outpouching and enlargement of the left atrial appendage ( 17 ), which is generally considered to be either congenital or acquired as a result of mitral valve disease or syphilitic myocarditis ( 18 ). Herein, we report on a rare congenital giant LAAA, causing acute cerebral infection and refractory AF.…”

“…TTE usually shows a large saccular echo-free structure laterally to LV. It can, however, hardly in most cases show the connection and communication between the LA and the echo-free cavity and, therefore, cannot make the definite diagnosis of LAAA in many cases and sometimes make the diagnosis mistakenly as a pericardial cyst or effusion ( 3 , 17 ). Khaled A. Shams reported a case with aneurysmally dilated LA pushing the heart to the right side, and thus a dextro-posed heart was misdiagnosed as dextro-cardia with rheumatic heart disease and AF for a long time till the disease progressed to cardiogenic shock ( 29 ).…”

BackgroundCongenital left atrial appendage aneurysm (LAAA) is a rare cardiac anomaly with a variety of presentations, from being asymptomatic to potentially serious complications such as systemic thromboembolism and atrial tachyarrhythmia.Case PresentationWe report a case of congenital giant LAAA in a 35-year-old man presenting with acute massive cerebral infarction and atrial fibrillation (AF) with rapid ventricular rate. The AF was refractory to conventional antiarrhythmic agents, such as amiodarone and electrical cardioversion, but restored and maintained sinus rhythm after surgical resection of LAAA. The patient remained free of events and was in sinus rhythm during half-year follow-up.ConclusionGiant LAAA has the potential causing serious complications and should be managed surgically in most cases.
