1. Evaluation of the aortic root with ECG-gated computed tomography (CT), including multi-planar reformats and three-dimensional (3D) images, allows for accurate measurement of aortic dimensions and pre-operative evaluation of anatomy.  2. Cross-sectional imaging with CT and MRA is crucial not only in the pre-operative evaluation of patients with aortic root pathology, but also assessment of post-procedural results and complications. 3. Surgical techniques include composite valve graft (CVG), Ross procedure (pulmonary autograft), cadaveric homograft, xenograft (pig-root/Medtronic freestyle), and valve sparing aortic root repair (including a variant of the Tirone David-V reimplantation technique, V-SARR).  

• Etiology of aortic root pathology including atherosclerosis, genetic/congenital conditions, dissection, bicuspid aortic valve, infection/inflammation • Review of surgical anatomy: sinotubular junction (STJ), sinuses of Valsalva (SOV), and aortic anulus • Normal and abnormal dimensions of the aortic root • Imaging and post-processing techniques for pre- and post-operative evaluation • Indications for aortic root repair • Surgical techniques • Post-operative imaging findings and complications • Sample cases • Review of key learning points
