Abstract:
In this video tutorial we demonstrate our technique of root reinforcement of the pulmonary autograft in a Ross operation. This technique is being used with increasing frequently to prevent the formation of an aneurysm of the pulmonary autograft. The patient presented in the video has a bicuspid aortic valve with severe symptomatic aortic valve stenosis and moderate regurgitation. After harvesting, the pulmonary autograft it is sized and a 3- or 5-mm oversized Valsalva vascular prosthesis is chosen for reinforcement and to prevent formation of an aneurysm. Sizing depends on the amount and thickness of muscle in the pulmonary autograft.

Reinforcement
Positive reinforcement occurs when a behavior is followed by the presentation of a rewarding stimulus, increasing the frequency of that behavior. For example:
