Ross Procedure With Pulmonary Autograft Reinforcement

Wednesday, July 11, 2012


The Ross procedure is a valuable alternative for the surgical treatment of aortic valve disease in adolescent and young adult. However, neo-aortic root dilatation resulting in valve regurgitation is not uncommon. This video demonstrates the authors' technical modification that prevents this complication.

We present the operative steps in the Ross procedure with pulmonary autograft reinforcement in a 16 year-old male. The patient presented with both stenotic and regurgitant congenital bicuspid aortic valve disease associated with an aneurysm of the ascending aorta.

Initially, supra-commissural ascending aorta replacement and aortic valve repair procedure were planned. Peri-operative TEE revealed the persistence of a residual, significant transvalvular gradient. A Ross procedure with pulmonary autograft reinforcement using a 24 mm Dacron conduit was then performed.

Normothermic cardiopulmonary bypass and intermittent antegrade warm blood cardioplegia were used. The result was satisfactory, and the patient was discharged home in a timely fashion.


Any developmental growth of the autograft is probably negated by the 24 mm Dacron , hence negating the main paediatric advantage of the procedure the late David Ross popularised. Is this a concern limiting the application of the Dacron re-enforcement to fully-developed adults? In the gender and age group of your patient, Devereux at al have calculated a mean diameter of the aortic root of 3.1
