The Ross procedure (or pulmonary autograft) is a cardiac surgery operation where a diseased aortic valve is replaced with the patient's own pulmonary valve. A pulmonary allograft (valve taken from a cadaver) is then used to replace the person's own pulmonary valve. The Ross procedure (or pulmonary autograft) is a cardiac surgery operation where a diseased aortic valve is replaced with the patient's own pulmonary valve.
The aorta is opened and the aortic valve is inspected. Once suitability for the Ross procedure has been determined, the pulmonary root autograft is excised. As the aortic root is excised, the coronary artery ostia are excised as buttons with adjacent aortic wall tissue. In children, implantation of the autograft is generally performed as a root replacement.
