Aortic valve repair is a new development with old roots. In the past 20 years, marked progress has been made in understanding the normal anatomy of the aortic valve and the interrelation between cusps and root. Aortic dilatation is the single most frequent pathogenetic factor in aortic regurgitation, accompanied by cusp pathology, that is, prolapse or congenital anomaly in most industrialized countries. Frequently, aortic and cusp pathology coexist. Different operative techniques have been established for correction of aortic and cusp pathology. Experience has shown that the combined application of repair procedures will lead to good results if normal valve and cusp configuration is achieved. Some congenital anomalies may require design alteration of the aortic valve. Low-operative mortality rates have been reported consistently. When adequate repair durability is achieved, the incidence of valve-related complications is lower than what has been reported for valve replacement. Aortic valve repair is currently in transition from surgical improvisation to a reproducible operation and an option for many patients with aortic regurgitation. Current research focuses on some special aspects, such as stabilization of the basal ring, ideal material and technique for cusp replacement, and more objective information on ideal valve configuration.
