Abstract
Aortic valve repair is an attractive concept because it offers the possibility of valve competence without structural deterioration due to nonviability and it precludes the need for anticoagulation. Enthusiasm for aortic valve repair has been debatable over the past 45 years due to the inherent technical difficulties and poor mid-term results. Renewed interest in the concept of aortic valve repair has paralleled the development of valve-sparing aortic root replacement over the last 20 years.
Attempts at aortic valve repair began in the late 1950s before and shortly after the availability of cardiopulmonary bypass with techniques like circumclusion, bicuspidization, aortic and annular plication, and annuloplasty.
These techniques, though novel, were not very successful, and once valve prostheses became widely available, aortic valve repair was nearly abandoned in the late 1960s. Later, Carpentier’s innovations of mitral valve repair techniques in the 1970s and 1980s generated renewed interest in aortic valve repair. Many techniques were described such as annuloplasty, midleaflet excisions for prolapse, commissurotomy, leaflet shaving for restricted cusps, and pericardial leaflet extension .
