Abstract: what kind of lesions can occur in patients with valvular heart disease? 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.
What are the symptoms of valvular heart disease and the 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:
1, mitral stenosis
If the flap is in good condition, it is only the junction adhesion or mild flap damage, and may be used for closed 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 cusp damage
Tricuspid valve replacement surgery is usually 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 stenosis in the elderly is mostly congenital aortic valve two valve deformity caused by calcification. Aortic valve replacement surgery.
5, aortic valve insufficiency
Aortic valve insufficiency can be caused by the enlargement of the valve ring, the laceration of the leaf, the curling or prolapse. Valve replacement surgery. Only mild aortic valve prolapse may be a plastic surgery.
6, pulmonary valve disease
Congenital malformations, the need for valve replacement, the need for the implementation of the right ventricular pulmonary artery bypass.
Relative contraindications to artificial heart valve replacement surgery
Experts stressed the relative contraindications to artificial heart valve replacement: 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.
