What is the normal value of infant heart ultrasound?

When infants and young children are very young, parents worry that their children may have some problems, so they do cardiac ultrasound examinations for their children. The cardiac ultrasound examination is mainly used to diagnose whether the child's heart is abnormal, to see if the child has congenital heart disease, and to check whether the child's heart is damaged or has arrhythmia. If the child's heart is normal, the value is normal. So what is the normal value of infant cardiac ultrasound?

Reference for normal values ​​of fetal heart ultrasound

AOD: aortic diameter, normal value 27mm, LAD: left atrial end-diastolic diameter, normal value 27mm, IVSd: interventricular septum end-diastolic thickness, normal value 7-12mm, RADd, right atrial diameter, normal value 43(+/-)4mm, LVPWd: left ventricular posterior wall end-diastolic thickness, normal value 7-11mm, average 9mm, FS: left ventricular internal diameter shortening rate, 34-44%, PeakA: A peak pressure difference, PeakE: E peak pressure difference, E/A: the ratio of the peak blood flow velocity of the rapid filling of the left ventricle in the early diastole to the peak blood flow velocity of the left atrial contraction. Normal value 1.7+/-0.4. : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : :

The patent ductus arteriosus and foramen ovale in a newborn may not close by themselves until the age of 2 during the child's growth. Even if there is some uncertainty, it will not have a big impact. Atrial septal defect of 4 mm is not very serious.

Usually it can close by itself at the age of one year

Atrial septal defect is caused by the incomplete development of the tissues that make up the atrial septum during the embryonic period.

Some smaller cases of type II atrial septal defects may close spontaneously within one year after birth, but are unlikely to close spontaneously within two years after birth. For simple type II atrial septal defect or type II atrial septal defect with partial right pulmonary venous anomalous return, if the ratio of pulmonary circulation blood flow to systemic circulation blood flow exceeds 1.5, surgical treatment should be considered. The most appropriate age for surgery is 4 to 5 years old. Early surgical treatment can prevent increased pulmonary circulation resistance and right heart failure. If congestive heart failure presents in infancy and childhood and medical surgery fails to control heart failure, surgery should be performed as soon as possible.

Above we introduced all the normal values ​​for reference and comparison after the infant's heart has been done with color Doppler ultrasound. If there is any abnormality in the heart of your pregnant infant, you must diagnose the child from these aspects. If the diagnosis is positive, you must give the child timely treatment. The values ​​for infants with damaged and non-damaged hearts are definitely different.
