Giant Left Atrial Aneurysm in a 15-Month-Old Child
A15-month-old boy with an 8-week history of breathing difficulty was brought to the accident and emergency department in atrial fibrillation. Clinical examination demonstrated moderate cardiac failure, and a chest radiograph showed gross enlargement of the mediastinal/cardiac silhouette (Figure 1). An echocardiogram showed an aneurysmal mass arising from the left atrium (Figure 2). The child was anticoagulated and given digoxin and frusemide. He unfortunately developed a mild right hemiparesis, presumably from a thromboembolic event. Two days later, a giant aneurysm of the left atrium was resected at surgery (Figure 3). A small portion of thrombus was removed from the appendage. Sinus rhythm resumed immediately, and the child made a good recovery. At the time of discharge, the hemiparesis had significantly improved.
