Giant Aortic Root Aneurysm in Marfan's Syndrome.

A 25-year-old man came to our clinic with the complaints of exertional palpitations and dyspnea. He had skeletal features suggestive of Marfan's syndrome. Contrast-enhanced computed tomography confirmed aneurysmal dilation of the aortic root and the proximal part of the ascending aorta. The patient was advised to undergo Bentall procedure for replacement of the aortic valve, aortic root, and ascending aorta. Marfan's syndrome is a connective tissue disorder with autosomal-dominant inheritance. Patients have a predisposition for progressive aortic root and ascending aortic dilation, and should undergo periodic echocardiographic monitoring.
