Congenital Left Atrial Appendage Aneurysm Research Articles

Left atrial appendage aneurysm enlarged in the neonatal period.

We describe a newborn with a congenital left atrial appendage aneurysm. The aneurysm size did not change prenatally. However, it rapidly enlarged after birth. MRI was useful for assessing the aneurysm extent and exact size, and for diagnosis. Respiratory distress and feeding difficulties appeared, and surgery was performed. These symptoms disappeared post-operatively. The patient is alive without complications or recurrence.

A CASE REPORT OF CONGENITAL GIANT LEFT ATRIAL APPENDAGE ANEURYSM WITH THROMBUS PRESENTING AS ATRIAL ARRHYTHMIA.

Congenital left atrial appendage aneurysm are a rare entities and are caused by congenital dysplasia of the atrial muscle. Less than 100 cases have been reported in literature so far. Patients usually present with dyspnoea ,palpitations ,thromboembolic phenomenon in their 3rd decade with slight higher preponderance in females.In asymptomatic individuals the condition is often diagnosed incidentally during cardiac imaging . We hereby report a case of 30 year old male with a giant LAAA containing thrombus presenting with palpitations diagnosed with echocardiography and cardiac MRI. The patient successfully underwent aneurysmal resection sugery, post which atrial arrhthias stopped and symptoms relieved. Therefore,even though rare,if a young patient presents with atrial tachyarrthymia with no other associated cardiac pathologies, a LAAA should be ruled out. Since this condition has been shown to be associated with increased morbidity and mortality. A transthoracic echocardiogram or even better,a TEE colour Doppler echocardiogram may suggest the diagnosis by demonstrating the exchange of blood between LA and LAAA. Surgical resection is the standard modalitiy of treatment even in asymptomatic individuals to reduce risk of associated complications. Learning objectives : It is a rare case of giant left atrial appendage aneurysm, few cases have been reported, LA appendage aneurysm usually present as atrial arrhythmias ,stroke or as incidental diagnosis on imaging.Though patients may be asymptomatic it still requires operative intervention since it has very high risk of atrial arrhythmias and thrombus formation which result into stroke.Therefore, if a young patient presents with atrial tachyarrthymia with no other cardiac pathologies, LAAA should be ruled out.

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.

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.

GW29-e1577 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

A Novel Technique of Repair of Congenital Left Atrial Appendage Aneurysm using Bovine Pericardial Patch

A congenital left atrial appendage aneurysm is a rare cause of supraventricular arrhythmias and dyspnea in young adult. Resection of the aneurysm is uniformly recommended in order to prevent life-threatening systemic embolization. We describe 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 under sizing and deformation of the left atrium.

A rare case of giant congenital left atrial appendage aneurysm in a 4-month-old child

Aneurysm of the left atrial appendage is a rare pathological condition, especially during infancy. We describe the case of a 4-month-old child with a giant congenital aneurysm of the left atrial appendage.

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 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.

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.

An incidentally diagnosed asymptomatic congenital left atrial appendage aneurysm

Left atrial appendage aneurysm is a rare cardiac anomaly. It can be congenital in origin or acquired secondary to inflammatory or degenerative processes. As it may cause potentially lethal arrhythmias or thrombi, surgical treatment is needed immediately after the diagnosis. In this article, we report a case of an asymptomatic three-year-old boy with a congenital left atrial appendage aneurysm. The patient was successfully treated with surgical resection of the aneurysm.

Off-pump snare technique for congenital left atrial appendage aneurysm

Left atrial appendage aneurysm is an extremely rare anomaly and as such has been rarely imaged or seen intraoperatively with very little accumulated management experience. The available scant published literature stresses resection on cardiopulmonary bypass as the safest and by far the most commonly applied technique. We suggest a novel alternative imaging-guided management utilising an off-pump tourniquet snare technique under live transoesophageal echocardiography.

The dangerous fifth chamber : congenital left atrial appendage aneurysm : case report

Aneurysms of the left atrial appendage are extremely rare. Enlargement of the left atrial appendage can be congenital or acquired. Dysplasia of the left atrial muscles leads to congenital left atrial appendage aneurysm and usually presents as atrial tachyarrhythmia or embolic events in the second or third decade of life. We report a case of an asymptomatic 12-year-old child with a congenital left atrial appendage aneurysm. Transthoracic and transoesophageal echocardiography demonstrated a large left atrial appendage aneurysm without thrombus or spontaneous echo-contrast. The patient was successfully treated with surgical resection of the aneurysm.

A giant left atrial appendage aneurysm with a large pinball-like thrombus in a 2 year old

Congenital left atrial appendage aneurysm is very rare. We describe a giant left atrial appendage aneurysm with a pinball-like mobile thrombus in a 2-year-old child with cardioembolic stroke. Patient underwent successful surgical resection of the aneurysm.

Atrial tachycardia in congenital left atrial appendage aneurysm: three-dimensional computed tomography imaging with electro-anatomical mapping

A 29-year-old woman was admitted for the evaluation of atrial tachycardia (AT) associated with palpitation during exercise. She had been diagnosed with a left atrial appendage (LAA) aneurysm at the age of 19 years. She was followed by echocardiography annually because she was asymptomatic, and evidence of thrombus formation and/or atrial tachyarrhythmia was not found. She developed AT 2 months before admission. The 12-lead electrocardiogram (ECG) revealed AT with a 2:1 ventricular response ( Panel A ). The P-wave morphology indicated the origin of AT as the superior …

Congenital left atrial appendage aneurysm diagnosed by fetal echocardiography

A newborn infant was evaluated because of a large cystic mass adjacent to the left atrium on prenatal ultrasound. The diagnosis was an aneurysm of the left atrial appendage. Most cases of this rare lesion are recognized between the 2nd and 4th decades of life. The present case, however, was detected on fetal echocardiography. The patient showed significant mitral regurgitation caused by the compression of the left atrioventricular groove. Simple aneurysmectomy without mitral valvuloplasty was sufficient to relieve significant mitral regurgitation in this case.

Congenital Left Atrial Appendage Aneurysm: A Case Report and Brief Review of Literature

A 28-year-old woman with congenital aneurysm of the left atrial appendage was successfully treated by aneurysmectomy and is reported for its rarity. The exact diagnosis is relatively easy to make by contrast echocardiography, magnetic resonance imaging, and/or computerised tomographic angiography, provided the possibility is entertained. Because of supraventricular arrhythmias and systemic thromboembolism, surgical resection was deemed the best curative option to avoid further episodes and recurrence. Published reports detailing the diagnostic evaluation and surgical management for congenital left atrial appendage aneurysm are also discussed.

Off-Pump Excision of Left Atrial Appendage Aneurysm: A Case Report

Isolated congenital intrapericardial aneurysm of the left atrium (LA) or the left atrial appendage (LAA) is a rare anomaly [Zhao 1999]. The patient usually presents with features of systemic embolization, serious arrhythmia, and severe congestive cardiac failure as a complication, which can be fatal. Once the condition is diagnosed, surgery is indicated [Zhao 1999]. We report a case of congenital left atrial appendage aneurysm in a woman who underwent excision of the same.
