1) the development of atrioventricular valve, if well developed, has a good plastic effect and a good surgical effect.

2) Whether the postoperative pulmonary artery pressure can be effectively reduced, it is unlikely that your child will have organic changes in pulmonary vessels at present. At present, pulmonary hypertension is mainly caused by large shunt and mitral regurgitation. If the pulmonary vascular resistance is not high, the pulmonary artery pressure can be reduced after operation, and the surgical effect is better.

3) Whether the ventricular development is balanced, according to your child's ultrasound results, it does not suggest that the left and right ventricles are unbalanced, so it is not considered for the time being.

It is recommended to operate for 3-6 months. After 6 months, the pulmonary vessels will undergo organic changes, pulmonary vascular resistance will increase, and pulmonary hypertension crisis will easily occur after operation, so the operation age should not be too early or too late.

Long-term effect of operation: If atrioventricular valve is dysplasia, plastic surgery is indeed a very difficult problem, which may require valve replacement, and may require valve replacement many times in one's life. Of course, the possibility is relatively small, and most children can improve valve regurgitation after the first valve plastic surgery. However, it is still necessary to follow up the situation of atrioventricular valve reflux for a long time after operation, and a considerable number of children still need valve replacement or valve plastic surgery for a long time after operation.

I wish your child a speedy recovery.
