Pre- and Postoperative Imaging of the Aortic Root

Area of Science:

• Cardiovascular Imaging
• Radiology
• Cardiac Surgery

Background:

• Three-dimensional imaging using computed tomography (CT) and magnetic resonance imaging (MRI) is essential for evaluating the aortic root.
• These imaging modalities possess distinct strengths and weaknesses that necessitate careful consideration within specific clinical scenarios.

Purpose of the Study:

• To provide a comprehensive overview of current aortic root imaging techniques.
• To detail normal anatomy, pathological conditions, surgical interventions, and postoperative complications related to the aortic root.
• To highlight potential imaging pitfalls encountered in the interpretation of aortic root studies.

Main Methods:

• Review of current literature and imaging techniques for aortic root assessment.
• Discussion of anatomical variations and pathological conditions affecting the aortic root.
• Analysis of various surgical repair techniques and their associated imaging findings.

Main Results:

• CT and MRI are valuable for characterizing aortic root anatomy and pathology.
• Knowledge of specific conditions like Marfan syndrome, bicuspid aortic valve, and connective tissue disorders is vital.
• Various surgical approaches exist, including composite valve grafts and aortic root reconstruction with valve preservation.
• Postoperative imaging requires awareness of potential pitfalls such as graft folds and hemostatic agents, and complications like pseudoaneurysms and infection.

Conclusions:

• Accurate interpretation of pre- and postoperative aortic root imaging relies on a thorough understanding of normal anatomy, surgical procedures, and potential complications.
• Radiologists must be proficient in utilizing CT and MRI for comprehensive aortic root evaluation.
• Familiarity with imaging pitfalls and postoperative complications improves diagnostic accuracy and patient management.
