Aneurysm of the left atrium

Congenital aneurysms of the left atrium: recognition by cross-sectional echocardiography.

“…In this position, its origin from the back wall of the left atrium and its extent was best seen in the parasternal long-axis view; the deformity in the posterior wall of the left ventricle that the aneurysm produced was most obvious in the short-axis view. The presence of intracavitary thrombus in patient 2 is in keeping with observations in patients at surgery or postmortem examination,3' 14' 19 and underlines the po-tential danger of systemic embolus in all patients with this condition.…”

“…19 Angiography is the established mode of diagnosis, the aneurysm is visualized by direct injection of contrast into the left atrium or by left-heart follow-through of contrast from a pulmonary arteriogram. In some cases, however, angiography has been misleading, and the correct diagnosis has been established only at thoracotomy or at postmortem examination.8' 1 1 5-20 In this report, we describe cross-sectional echocardiographic findings in three patients with aneurysmal dilatation of the left atrial wall.…”

Intrapericardial Left Atrial Aneurysm: Noninvasive Diagnosis

“…Congenital intrapericardial aneurysm of the left atrium is a rare cardiac abnormality: Only 20 such cases have been reported in the literature [2][3][4][5]. This left atrial aneurysm involves the atrial wall, the atrial appendage, or both [2], and the pericardium is normal and intact.…”

Aneurysm of the left atrial appendage

“…Exceptions are the patient reported by Parmley (10) who had an ejection murmur due to an asSociated atrial septal defect and two patients (5, 7) in Whom mitral regurgitation was responsible for a pansystolic murmur. The electrocardiogram is normal or may show notching of the P wave (5,6,10).…”
