Abstract
The arterial switch operation (ASO) is the procedure of choice today for simple transposition of great arteries. This procedure results in anatomical correction of the defect and long-term complications are infrequent. We present what may be the first report of multiple aortic aneurysms in a 6-week-old baby boy 4 weeks post-ASO. Initial diagnosis was made by transthoracic echocardiography, which was confirmed by computed tomographic angiography and surgical inspection. The aneurysms were repaired surgically with two aortic homograft patches without complications.
