Aortic complications after aortic valve replacement in patients with dilated ascending aorta and aortic regurgitation.

Abstract

Patients with a dilated ascending aorta (> or = 40 mm diameter) were more likely to encounter complications of the aortic dissection or enlargement after AVR than those with a small ascending aorta. Surgery to prevent aortic dissection or enlargement must be selected in patients with mildly dilated ascending aorta and hypertension.
