[Aneurysms of the ascending aorta; total replacement with reimplantation of the coronary arteries (author's transl)].

The replacement of the entire aorta and the aortic valve is the procedure of choice in aneurysms involving the aortic annulus. This method, which necessitate the reimplantation of the coronary arteries, is, however, sometimes difficult and carries a greater operative risk of bleeding problems. Our experience of 15 such cases lead us to propose some modifications (such the use of an independent coronary conduit and the atrial drainage of the peri prosthetic space) in order to make the operation simple and safer.
