Abstract: 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. Patients with valvular heart disease who are unable to undergo a surgical treatment of cardiac valve disease should be treated as long as the whole body is allowed. There is no absolute limit on the age of patients with valvular heart disease. Common lesions are the following:
1, mitral stenosis: if the flap activity is good, only for 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.
2, mitral regurgitation: mitral valve annulus enlargement or the junction of the limitations of the valve leaf curl, you can strive for the implementation of direct vision surgery. 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.
3, three pointed flap damage: usually do not change the flap valve three. Only when the disease is serious, valve replacement surgery.
4. Aortic stenosis: congenital aortic valve stenosis can often be performed in young adults during open heart surgery, aortic valve stenosis in elderly patients with congenital aortic valve is mainly caused by calcification of the two valve deformity. Aortic valve replacement surgery.
5, aortic valve regurgitation: aortic valve insufficiency can be enlarged by the valve ring, flap tear, curl or prolapse caused by. Valve replacement surgery. Only mild aortic valve prolapse may be a plastic surgery.
6, pulmonary valve disease: congenital malformations, rarely need to change the valve, often need to implement the right ventricular pulmonary artery bypass.
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.
