Congenital giant aneurysm of the left atrial appendage in an infant

Abstract: Aneurysm of the left atrial appendage is a rare pathological condition. We describe the diagnostic work-up and surgical management of a child with giant congenital aneurysm of the left atrial appendage. C ONGENITAL LEFT ATRIAL APPENDAGE ANEURYSM IS a very rare congenital heart disease, 1-7 with potentially lethal complications. 1-3 We report a case of congenital left atrial appendage giant aneurysm, leading to left ventricular compression and progressive mitral valve regurgitation, which was successfully opera… Show more

“…[2][3][4][5] As in our patient, two of the four cases were detected on fetal echocardiography and confirmed at birth [4][5] ; the others were diagnosed at 3 and 18 months of age, following the investigations of a murmur and distant heart sounds, respectively. 2,3 All infants were initially asymptomatic at birth except one who demonstrated mild respiratory distress. 5 To our knowledge, no previous reports of congenital giant LAA aneurysms have discussed noninvasive imaging with cardiovascular magnetic resonance (CMR).…”

“…These patients may be asymptomatic and/or may present with dyspnea, palpitations, and thromboembolic events . The most common complications are life‐threatening thromboembolic events and supraventricular tachyarrhythmias . Transthoracic echocardiography plays a very important role in the diagnosis of LAAA; in addition to the absence of pericardial defect, there is a direct link between the aneurysm and the normal left atrial space.…”

“…1 These aneurysms probably increase in size as the patient ages. 2 Despite its congenital cause, symptoms usually do not arise until the second or third decade of life. 1,3 Once the aneurysms reach a larger size, they predispose the patient to supra-ventricular arrhythmias, cardiac dysfunction, atypical chest pain episodes due to compression of the left coronary artery or any of its divisions, an increased risk of intra-atrial thrombus formation, and systemic embolisation.…”
