Aortic valve Aortic valve The aortic valve is a valve in the human heart between the left ventricle and the aorta. It is one of the two semilunar valves of the heart, the other being the pulmonary valve. The heart has four valves and the other two are the mitral and the tricuspid valves. The aortic valve normally has three cusps or leaflets, although in 1–2% of the population it is found to congenitally have two leaflets. The aortic valve normally has three cusps however there is some discrepancy in their naming. They may be called the left coronary, right coronary and
Mitral valve annuloplasty are believed to be key to optimize leaflet coaptation and to minimize tissue stresses. The challenge of mitral valve annuloplasty is to improve the diseased and distorted shape of the mitral valve and to reestablish the physiological configuration, while preserving normal annular dynamics. Today, cardiac surgeons can select from a variety of annuloplasty devices, flexible, semi-rigid, or rigid, incomplete or complete, planar or saddle-shaped, adjustable and non-adjustable. While the general goal of all devices is the same, namely to increase leaflet coaptation and to support the posterior annulus against dilation, flexible bands are designed to maintain the three-dimensional contour of
