[Successful report of total aortic root replacement by a new technique].

We employed a new procedure of the total aortic replacement in 2 cases which is made of composite graft and reimplantation of the coronary arteries by direct suture technique. These patients took good clinical course and were discharged after operation. We believe that this procedure is a very useful for annuloaortic ectasia or dissecting aortic aneurysm involved coronary artery with aortic regurgitation.
