Abstract: congenital valvular disease of children is mainly caused by mitral regurgitation and common atrioventricular valve, acquired or acquired rheumatic heart disease and infective endocarditis.

Children's heart valve surgery what are the precautions? Children with congenital valvular heart disease with mitral regurgitation and common atrioventricular valve, congenital or acquired mainly rheumatic heart disease and infectious endocarditis caused by heart valve can be all involved, adhesion, thickening, stenosis, curling etc..

There were few complications after valve replacement in children, and there was no difference between early survival rate and adult. But the biggest problem encountered is the growth and development, the effective diameter of artificial valve is not large enough, after a period of time also need to re replacement. At the same time lifelong anticoagulation will bring a lot of inconvenience, if there is a mistake, it will cause bleeding and other serious consequences.

Children are the main factors of heart valve replacement surgery is the following two points:

1. There is no ideal substitute for heart valve in children, and it is difficult to avoid the development of small valve;

2, valve replacement after the variation factors, different from the adult children, valve replacement indications strictly, on the principle of valvular disease as far as possible the use of repair method, only when the valve damage has been repaired before considering for valve replacement surgery.

Therefore, for children with heart valve surgery, should be based on the repair and repair, it is not enough, before considering valve replacement. Of course, it is also based on the doctor's experience, to be a comprehensive judgment.

Aorticvalve testify: systolic pressure gradient is greater than 60 mm Hg, had aortic stenosis patients with myocardial strain and clinical or hemodynamic examinations showed that left ventricular dysfunction in patients with aortic regurgitation or ECG exercise, including chest cardiac enlargement, left ventricular end diastolic pressure increased or decreased ejection fraction.

Shanghai Yuanda Cardiothoracic Hospital, director of the introduction of the road, for the replacement of the valve if the child, most of the use of mechanical valves, general children in the 7~8 years old to install artificial heart valve. However, due to some shortcomings of the mechanical valve, both at home and abroad are currently studying the transformation of the same biological valve. This kind of valve can not only maintain the vitality of the tissue, but also do not produce antigen reaction (the body's rejection of foreign substances). Meanwhile, the utility model has the advantages of long service life and convenient use, and is especially suitable for children.
