Although aortic valve repair has been performed since the early days of open-heart surgery, the introduction of intraoperative transesophageal echocar-diography (TEE) and better understanding of the functional anatomy of the aortic valve have helped the development of newer surgical approaches to aortic valve repair in patients with aortic insufficiency (AI) or aortic root aneurysm. Transesophageal echocardiography is the best diagnostic tool to determine the mechanism of AI and the geometric relationships among various components of the aortic root, to select candidates for aortic valve repair, and to evaluate valve function in the operating room. In addition, TEE can help in the evaluation of cusp morphology, prolapse, and degree of coaptation, and in the recognition of sinotubular-junction dilation. Aortic valve repair is feasible in a high proportion of patients with isolated AI caused by cusp prolapse, dilation of the aortic root, or both. Several procedures have been developed to repair aortic cusps during conservative procedures on the aortic valve.
