Validation of MRI Instead of CT to Follow-up Ross Procedure With Loose Jacket Technique

"• Cardiac MRI Protocol~The cardiac MRI protocol will include cine imaging, aortic flow, and 3D navigator of the aorta. These sequences will be performed to assess aortic root dimensions, including aortic root, sinuses of Valsalva, and sinotubular junction and ascending aorta diameters.~• CT Aortography Protocol:~The CT aortography protocol will include non-contrast and contrast-enhanced CT imaging. The non-contrast images will be used for calcium scoring, while the contrast-enhanced images will be used to assess aortic root dimensions"
