During the 31 years since the initial Ross procedure, data have been collec
ted that have been helpful in assessing long-term performance of the autogr
aft. The ongoing study of the pulmonary autograft supports the use of the R
oss procedure in young patients, in females of childbearing age, and in pat
ients with congenital aortic stenosis and complex left ventricular outflow
tract obstruction. We continue to see little or no thromboembolism despite
no anticoagulation therapy. The remarkable ability of the autograft to grow
in children is extremely beneficial. Additionally excellent results have b
een obtained in some series for the treatment of endocarditis. Recently, th
e autograft has performed similarly to a normal aortic valve under high str
ess. Changes in implantation techniques transitioning from subcoronary to r
oot replacement and performing annular narrowing has decreased the incidenc
e of early regurgitation. A potential for an immune response with resulting
pulmonary stenosis and possible early explantation of the pulmonary homogr
aft exists; however, overall, results of the Ross procedure are excellent a
nd highly reproducible.
