Intrapericardial left atrial appendage aneurysm

An intrapericardial left atrial appendage aneurysm is described in a 36 year old female. She was asymptomatic except for intermittent palpitations. The aneurysm was initially diagnosed by 2D-echocardiogram and confirmed by pulmonary cineangiogram. In addition to compression and indentation of the anterolateral wall of the left ventricle, hypokinesis was noted, which we believe has not been reported previously, in association with the left atrial appendage aneurysm, and which improved after surgical resection. The patient is symptom-free at a 5 year follow-up. A review of the literature is presented.

Congenital aneurysm of the left atrial appendage

Congenital aneurysm of the left atrial appendage is quite infrequent.Most instances are asymptomatic. Patients can report a varietyof symptoms, one of the most frequent being onset of auriculartachyarrhythmia. Various imaging techniques are useful in diagnosisand allow the differential diagnosis with other pathologies. We describe the case of a 24-year-old male with congenital aneurysmof the left atrial appendage. The patient presented with auricularfibrillation. Diagnosis was based on transthoracic and trans-esophagealechocardiography, and the patient was treated by surgical resectionof the aneurysm under extracorporeal circulation.     

Congenital aneurysm of the left atrial appendage

Congenital aneurysm of the left atrial appendage is a rare anomaly, usually presenting in adult life. We report the case of a 31-year-old woman with a marked prominence of the upper left heart border at the chest X-ray in whom the diagnosis of congenital aneurysm of the left atrial appendage was confirmed by cross-sectional echocardiography and computed tomography. Up to few years ago angiography was considered the method of choice in establishing the diagnosis. Cross-sectional echocardiography has recently become a safe and reliable method for diagnosing congenital aneurysm of the left atrium and should be considered in any case with abnormality of the profile of left atrium on the chest radiography.     

Congenital aneurysm of left atrial appendage.

Congenital aneurysm of the left atrial appendage is a rare anomaly, usually presenting in adult life. The case reported is that of a 55-year-old man who died of cerebral embolism originating from a thrombus in a congenital aneurysm of the left atrial appendage. The cardiac silhouette 11 years previously had suggested a cardiac tumour or a pericardial cyst. As judged frm 14 published cases, the major manifestations of these aneurysms are an abnormal cardiac silhouette in the x-ray, supraventricular tachycardia, and systemic embolism. Angiocardiography appears to be the method of choice in establishing the diagnosis. Resection of th aneurysm is the recommended form of treatment.     

Giant intrapericardial aneurysm of the left atrial appendage

A young patient is reported with an aneurysm of the left atrial appendage having supraventricular arrhythmias and a period of chest pain accompanied by a rise in cardiac enzymes. Compression of the left anterior descending coronary artery by the aneurysm was felt to be responsible for the myocardial injury.     

Massive left atrial appendage aneurysm presenting as supraventricular tachycardia

Left atrial appendage aneurysm is a rarely reported condition. Symptoms are absent in childhood and diagnosis is usually incidental. Systemic embolization or arrhythmia can bring these cases to medical attention. We report the case of a 12-year-old male with massive left atrial appendage aneurysm who presented with effort intolerance and supraventricular arrhythmia. The diagnosis was made by transthoracic echocardiography. Magnetic resonance imaging and left atriogram were also done before surgical resection.     

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.     

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.

Left atrial appendage aneurysm: echocardiographic diagnostic

The left atrial appendage aneurysm is a rare condition that frequently manifests itself by heart arrhythmias or thromboembolism. We report the case of a patient with left atrial appendage aneurysm, diagnosed by echocardiography and submitted to surgical resection.     

Treatment of congenital aneurysms of the left atrium and left atrial appendage.

We report 2 cases of congenital aneurysm, 1 of the left atrium and 1 of the left atrial appendage. The patients were 14 and 27 years of age, respectively. Their common symptoms were paroxysmal palpitations and dyspnea. Diagnoses were suggested by chest radiographic films that revealed prominent convexity at the upper left border of the heart and were confirmed by echocardiography, which demonstrated a large cystic mass attached to the left atrium in each case. Aneurysmectomy was performed through a median sternotomy or a left thoracotomy, with cardiopulmonary bypass in 1 patient and without it in the other. Both patients were discharged, free of symptoms, in sinus rhythm. We conclude that echocardiography can provide a clear diagnosis and that aneurysmectomy is the treatment of choice.
