Aortic valve replacement

The surgical treatment of aortic valve insufficiency is the same as aortic valve stenosis. There are two surgical methods: valvuloplasty and valve replacement. Valvuloplasty has a long history with the development of cardiac surgery. Prior to the advent of extracorporeal circulation, there were two surgical methods for the treatment of aortic valve insufficiency: one is ring contraction, and the other is valve valvuloplasty. In 1958, Lillehei et al. Used extracorporeal circulation for lobectomy or single valve leaflet expansion with Ivalon sponge for aortic annuloplasty. In 1960 Mulder et al. Reported different types of valvuloplasty methods. At present, valve suspension, annulus annulus and valve repair are commonly used. As early as 1952, Hafnagel first placed artificial valves in the descending aorta to correct aortic valve insufficiency, but failed to continue application due to the inability to improve coronary blood supply, the high incidence of embolism, and serious complications such as thrombotic infections. . In 1960, Harken and others first transplanted the cage ball valve to the normal aortic valve position, and then successively developed the same aortic valve transplantation, porcine aortic valve, bovine pericardial valve and other biological valves, as well as various mechanical valves, as heart valves. Replacement opens up broad prospects.
