Abstract
A girl with the Marfan syndrome is described who developed mitral regurgitation, an aneurysm of the ascending aorta, and severe aortic regurgitation. Complete surgical correction required mitral valve, aortic valve, and ascending aorta replacement with transplantation of the origin of the coronary arteries. The cardiovascular complications of the Marfan syndrome are discussed and the previously described surgical techniques for dealing with aortic or mitral involvement are briefly reviewed. A simpler and safer method for replacement of the complete ascending aorta with coronary artery transplantation is described.
