Ross Operation :  In this technically demanding operation, the aortic valve is replaced by patient's own pulmonary valve (autograft) and a pulmonary or aortic allograft (homograft) is used for replacing the pulmonary valve. The advantage of this operation is that the autograft in the high-pressure aortic position will last indefinitely. The homograft in the low-pressure pulmonary position, where even if it fails after long time, regurgitation is better tolerated.

The operation is done under cardio pulmonary bypass, using two venous cannulae and a single ascending aortic cannula.
