Congenital heart disease is an anatomical abnormality of the heart and large blood vessels caused by various adverse factors (such as viral infection in early pregnancy, exposure to radiation and cytotoxic drugs, nutritional deficiencies, psychological trauma, maternal diseases such as diabetes, hypercalcemia, and maternal age) during embryonic development (mainly in the early 12 weeks of pregnancy), or the failure to close channels that should close automatically after birth (such as the ductus arteriosus). (e.g., the ductus arteriosus) does not close (which is normal in the fetus). Congenital heart disease is the most common type of congenital malformation, with a prevalence of 0.4% to 1% among live births in China. The main adverse effects of congenital heart disease are: lack of oxygen to the organs affects the growth and development of the child or even dies soon after birth; increased blood flow to the lungs makes it easy to have repeated lung infections; abnormal blood flow increases the burden on the heart for a long time and leads to heart failure; induces malignant arrhythmia or even sudden death; prone to infective endocarditis; and economic pressure on the family. Common clinical manifestations include: shortness of breath, cyanosis, breastfeeding stoppage, slow growth, excessive sweating and irritability, recurrent pneumonia, children walking squatting, dizziness and palpitations, fatigue and chest pain, etc. Most congenital heart diseases can be screened by heart auscultation, and cardiac ultrasonography is the most convenient and easy, objective and reliable non-invasive examination means to diagnose congenital heart disease. The main treatments are interventional minimally invasive treatment and open-heart treatment. The specific need to go to the regular hospital treatment.
