Allograft aortic root replacement: standardization and simplification of technique.

A variety of surgical techniques for implantation of an allograft aortic valve have been described. Compounding this confusion, the host pathologic processes necessitating aortic valve or root replacement are many, often associated with asymmetry of the aortic root and valve annulus. These complexities can now be negated by routinely performing allograft aortic root replacement with pedicle coronary artery reimplantation in all situations. This procedure is described in a simple step-by-step manner that makes it amenable to all cardiac surgeons independent of experience.
