Safe treatment of congenital left atrial appendage aneurysm using lateral thoracotomy on a 3-year-old patient

Limited literatures report the management of congenital left atrial appendage aneurysm (LAAA) which is extremely rare. Chest X-ray firstly showed an enlarged left cardiac silhouette for a 3-year-old patient with pneumonia. Echocardiography and magnetic resonance imaging confirmed a large cyst attached to the left atrium. Aneurysmectomy was performed through lateral thoracotomy using step-by-step method and under the guidance of transoesophageal echocardiography. We aim to show the safety and efficacy of this approach applied to children associated with congenital LAAA.

Multimodality Imaging and 3D Modeling in Cardiac Surgical Planning: A Case of Infant with Isolated Left Atrial Appendage Aneurysm

We present here a case of an infant who was prenatally diagnosed with an isolated left atrial appendage aneurysm. Although asymptomatic, we proceeded with surgical resection due to rapid progression of aneurysm size. Multimodality imaging – transthoracic echocardiography, transesophageal echocardiography, and cardiac computed tomography – was used for procedural planning, from which a detailed 3D computational model and 3D print of this patient’s heart were created. The aneurysmectomy was performed at 6 months of age, with an uneventful postoperative course.

A novel technique of repair of congenital left atrial appendage aneurysm using bovine pericardial patch: A video presentation

Because of its rarity and association with life threatening complications like supraventricular arrhythmias, systemic embolization, congestive cardiac failure, prompt recognition of congenital left atrial appendage aneurysm is important in patients with an enlarged cardiac silhouette and a prominent convex bulge of the left upper cardiac border without carinal widening. We report here-in a new technique of resection of the congenital left atrial appendage aneurysm and anatomical reconstruction using a bovine pericardial patch under cardiopulmonary bypass, permitting us to avoid undersizing and deformation of the left atrium.

Huge left atrial appendage aneurysm revealed by chronic hiccups

Left atrial appendage (LAA) aneurysm is an extremely rare anomaly. So far, less than one hundred cases only have been reported worldwide. Revelation modes are dominated by complications such as arrhythmias and thromboembolic events. We herein report a pediatric case of huge congenital LAA aneurysm with an original revelation mode that has never been described before in medical literature.

Congenital giant left atrial appendage aneurysm: a case report

BackgroundCongenital left atrial appendage aneurysm (LAAA) is a rare cardiac anomaly with potentially serious complications, including life-threatening systemic thromboembolism, atrial tachyarrhythmia, and cardiac dysfunction. Currently, early surgical intervention is generally recommended to prevent these complications.Case presentationWe present a case of congenital giant LAAA in a female patient who successfully completed pregnancy and underwent caesarean section with no obvious complications. Surgical resection of the LAAA was performed 3 years later, at the onset of chest pain resulting from compression of adjacent cardiac structures by the LAAA.ConclusionSurgical resection is recommended for the majority of patients with LAAA because of potential LAAA-related severe outcomes. However, clinical monitoring may be an optional strategy for asymptomatic patients without intra-atrial thrombus or other complications. Precise evaluation with echocardiography and brain magnetic resonance imaging is valuable for the subsequent management of LAAA.

Congenital Left Atrial Appendage Aneurysm: Diagnosis and Management

Aneurysm of the left atrial appendage is rare. We sought to review the published literature on left atrial appendage aneurysm (LAAA) to address its epidemiology, pathology, clinical symptoms, diagnosis and management. We reviewed PubMed from 1962 to 2016 to find relevant LAAA cases using medical subject heading (MESH) terms “atrial appendage” and “aneurysm” as search terms. Statistical analysis was done using Minitab 17.0. One hundred and one cases of LAAA were identified. The symptoms do not arise until the second to the fourth decades of life. Palpitation, dyspnea and chest pain were common clinical symptoms. Echocardiography is considered to be the primary method of diagnosis. Other imaging modalities such as cardiac computed tomography (CT) and magnetic resonance imaging (MRI) are useful for ruling out the differential diagnoses. Surgical treatment is often recommended even in asymptomatic patients for prevention the thromboembolic complications. Seventy-four patients (73.2%) reported in the literatures were treated by surgical treatment. The prognosis is favorable, for freedom from recurrent symptoms and arrhythmia has been reported from 10 days to 8 years follow-up. Echocardiography is considered the initial diagnostic tool for LAAA. The associated high risk of life-threatening complications and the relative ease of surgical removal suggest that prompt evaluation should be considered in patients with lesions adjacent to the left heart border.

Congenital left atrial appendage aneurysm: A treacherous extra chamber

Left atrial appendage aneurysm (LAAA) without involvement of mitral valve is a rare anomaly caused due to dysplasia of atrial muscles. Patients may be asymptomatic or may present with palpitations, dyspnea, atypical chest pain, or thromboembolic complications. Treatment usually consists of surgical resection of the aneurysm, and prognosis postsurgery is very good. We herein report a case of a 4-year-old child who presented with palpitations and found to be having LAAA.

Giant left atrial appendage aneurysm compressing the left anterior descending coronary artery

Left atrial appendage aneurysm (LAAA) is a rare congenital structural heart disease. It is often diagnosed by echocardiography; however, other imaging modalities can add to its diagnosis and its potential effects on the surrounding structures. A 16-year-old boy presented with dyspnea and palpitation. Transthoracic echocardiography showed a large LAAA communicating with the LA through a narrow neck with impaired left ventricular (LV) systolic function. Multidetector cardiac tomography showed that the LAAA is compressing the left anterior descending artery. The LAAA was surgically resected followed by improvement of the LV systolic function.

Congenital Giant Left Atrium with Severe Mitral Valve Regurgitation.

A three-month-old male infant presented to the Royal Hospital, Muscat, Oman in April 2014 following two episodes of pneumonia. On presentation, the patient was not dysmorphic; however, he was tachycardic and tachypnoeic with severe respiratory distress. A pansystolic murmur was heard in his apex, radiating to the axilla. A chest examination showed bilateral wheezing and scattered crepitations. An abdominal examination revealed a soft abdomen with hepatomegaly (liver span of 12 cm), situated 4 cm below the right costal margin. Echocardiography and an angiographic volume-rendered reconstructed computed tomograph showed a giant left atrium measuring 7.4 × 4.7 cm [Figure 1]. The atrium had severe mitral valve regurgitation from poor coaptation of the mitral valve leaflets due to annulus dilation of 22 mm. The mitral valve apparatus and left atrial appendage were normal, excluding the associated left atrial appendage aneurysm. There was mild tricuspid valve regurgitation with a peak gradient of 90 mmHg (systemic blood pressure: 80/55 mmHg), indicating severe pulmonary hypertension. The left ventricle was moderately dilated—the left ventricular posterior wall dimension in diastole was 4 mm; the interventricular septum dimension in diastole was 4 mm; the left ventricular end diastolic dimension was 40 mm; and the left ventricular end systolic dimension was 18 mm. Normal ventricular systolic function was noted (ejection fraction: 62%). The right ventricle was compressed by the dilated left ventricle, with severe compression of the right atrium secondary to the dilated left atrium. The inferior vena cava and hepatic veins were dilated; however, the superior vena cava was compressed by the dilated left atrium with a mean gradient of 8 mmHg at its midportion. The dilated pulmonary veins drained normally to the left atrium. No intracardiac vegetation or thrombi were seen. These findings were confirmed by cardiac computed tomography (CT) angiography; severe compression of the left main bronchus was also observed [Figure 2]. The CT angiography also revealed a left atrial volume of 84 mL compared to a left ventricular volume of 10 mL. A chest radiograph of the infant revealed a persistent left-sided lung opacity [Figure 3]. Further abdominal ultrasonography and CT findings indicated eventration of the left hemidiaphragm with a raised spleen position corresponding to the opaque shadow seen on the chest radiograph. A diagnosis of a congenital giant left atrium (CGLA) was made. Figure 1A & B: A: Four chamber echocardiograph showing a giant congenital left atrium (white arrow) severely compressing the right atrium (red arrow) in a three-month-old male infant. B: Volume-rendered reconstructed computed tomography angiograph showing the giant ... Figure 2A & B: A: Axial computed tomography (CT) angiograph showing a giant congenital left atrium (black arrow) with left upper lobe and segmental right lower lobe atelectasis (red arrows) in a three-month-old male infant. B: Maximum-intensity CT angiograph projection ... Figure 3: Frontal chest radiograph of a three-month-old male infant with congenital giant left atrium showing a persistent left-sided lung opacity (arrow). This was determined by ultrasonography and computed tomography to be a raised spleen caused by eventration ... Despite cardiac anti-failure medications and inotropic support, a high-risk operation was performed to repair the mitral valve due to the cardiac findings and prolonged intubation. A posterior annuloplasty and a posterior left atrial wall excision were also carried out concurrently. The diagnosis of CGLA was confirmed during the course of the surgery. Following the operation, the left atrial dilation improved and the right ventricular systolic pressure decreased to 30 mmHg (estimated from the tricuspid valve regurgitation jet). Unfortunately, the moderate mitral valve regurgitation continued postoperatively and the infant died two weeks later due to severe cardiorespiratory compromise.

Paradoxical Response of Giant Left Atrial Appendage Aneurysm after Catheter Ablation of Atrial Fibrillation

A giant left atrial appendage (LAA) aneurysm is a very rare cardiac anomaly, and associated with the supraventricular arrhythmia including atrial fibrillation (AF) (1-3). Furthermore, the giant LAA aneurysm may be the main source of thrombosis in patients with AF (1-3). With technical developments of catheter ablation, the percutaneous electrical isolation of cardiac arrhythmogenic substrates has been considered as the effective strategy for management of drug-refractory AF (4). Additionally, Hof et al. (5) reported that a patient with AF and giant LAA aneurysm could be successfully treated by percutaneous pulmonary vein antrum isolation. Echocardiography is the first line imaging technique to detect the giant LAA aneurysm (2). Especially transesophageal echocardiography (TEE) allows clear visualization of the LAA, and can be effective for the diagnosis of giant LAA aneurysm and thrombi. However, TEE may provide a relatively narrow field of view in the delineation of entire parts of giant LAA aneurysm (2).

Combination of congenital left atrial appendage aneurysm in an infant with transposition of the great arteries: a previously unreported association

A 35-day-old boy weighing 4.5 kg was referred to our department from a general paediatric hospital due to low oxygen saturation. His transcutaneous oxygen saturation was 75%. Transthoracic echocardiography showed discordant ventriculo-arterial connections, a non-restrictive atrial septal defect, and patent ductus arteriosus, in addition to a 23 mm×10-mm left atrial appendage aneurysm. As far as we know, this association has not been reported previously in the literature.
