Abstract: the indication of artificial heart valve replacement surgery is mainly based on the degree of damage of the heart valve. All patients with severe valvular disease and can not do plastic surgery, as long as the general situation should be allowed for the implementation of valve replacement surgery. There is no absolute limit on the age of the patient.

Indications for prosthetic heart valve replacement surgery are based on the degree of damage to the heart valve. All patients with severe valvular disease and can not do plastic surgery, as long as the general situation should be allowed for the implementation of valve replacement surgery. There is no absolute limit on the age of the patient. There are several common lesions slightly:

Mitral valve stenosis: if the flap is good, it is only at the junction of adhesions or mild flap damage, can be used for closed expansion or open surgery. If the valve calcification or funnel like change, the need for valve replacement surgery.

Mitral valve regurgitation, enlarged mitral valve annulus, or restricted leaflet curvature at the junction of the mitral valve, may be used for direct vision. Mitral valve replacement surgery should be performed if the perforation of the leaf and the rupture of chordae et al. Mitral stenosis with mitral regurgitation, most of which require flap replacement.

Three tricuspid valve damage -- usually three cusps without flap replacement. Only when the disease is serious, valve replacement surgery.

Aortic valve stenosis congenital aortic valve stenosis can often be performed in young adults during open heart surgery, aortic valve stenosis in the elderly is mostly congenital aortic valve two valve deformity caused by calcification. Aortic valve replacement surgery.

Aortic valve insufficiency aortic valve insufficiency can be caused by enlargement of the valve ring, laceration of the leaf blade, curling or prolapse. Valve replacement surgery. Only mild aortic valve prolapse may be a plastic surgery.

Pulmonary valve disease, congenital malformation, seldom needs to be replaced, and the right ventricle pulmonary artery bypass is usually required.

Relative contraindications to artificial heart valve replacement surgery: rheumatic activity is not control or control in less than 3 months; heart failure complicated with myocardial ischemia damage such as aortic stenosis patients in advanced stage. If the heart function has improved, still strive for surgery. Patients with poor liver or kidney function or poor general condition. Bacterial endocarditis in patients with sepsis and multiple infections are not appropriate for surgery.
