The reason why the baby's heart is not growing well

Many diseases come from congenital problems. For example, during the infant development period, the baby's heart function is not well developed and there will be major defects. For example, congenital heart defects can cause heart disease, abnormal development of heart and blood vessels, and cardiovascular malformations. Patients need to undergo heart repair surgery for treatment to avoid many complications later on.

Congenital heart disease Congenital heart disease can be cured. It can be cured.

Congenital heart disease is a cardiovascular malformation caused by abnormal development of the heart and blood vessels during the fetal period. It is the most common heart disease in children.

Over the past 20 years, due to the development of advanced modern examination techniques (such as cardiac catheterization, cardiovascular angiography, color Doppler echocardiography and radionuclide cardiovascular angiography, etc.) and the progress of hypothermia anesthesia, extracorporeal circulation and cardiac surgery, many common congenital heart diseases can be accurately diagnosed and cured, and some complex heart malformations can also be treated surgically.

[Cause] ① Heredity is the main internal cause.

② Any factors that affect the development of the heart embryo during the fetal period may cause heart malformations, such as the pregnant mother suffering from rubella, influenza, mumps, Coxsackie virus infection, diabetes, hypercalcemia, etc., the pregnant mother is exposed to radiation; the pregnant mother takes anti-cancer drugs or drugs such as tocopherol.

Classification of congenital heart disease: According to the presence or absence of abnormal channels between the left and right sides of the heart or between the large blood vessels (large arteries and large veins), or according to the presence or absence of cyanosis, congenital heart disease is divided into ① left-to-right shunt type (latent cyanosis type): such as atrial septal defect, ventricular septal defect, and patent ductus arteriosus.

② Right-to-left shunt type (cyanotic type): such as tetralogy of Fallot, transposition of great vessels, etc.

③ Non-shunt type (non-cyanosis type): such as pulmonary artery stenosis, aortic coarctation, etc.

symptom

① The growth and development of children with this disease may lag behind that of children of the same age and they may be more susceptible to respiratory infections.

② The presence or absence of cyanosis depends on the nature of the heart deformity. For example, there is usually no cyanosis in the early stages of atrial septal defect, ventricular septal defect and patent ductus arteriosus, but cyanosis may occur after strenuous activities or crying or laughing. Cyanosis may occur in the late stages with age. In right-to-left shunt type congenital heart disease, severe heart malformations, such as tetralogy of Fallot, children may develop cyanosis after birth or within a few weeks to months, and the symptoms gradually worsen.

③ Auscultation of the heart: a systolic murmur can be heard at the left edge of the sternum. The murmur of ventricular septal defect is lower, louder, and coarser than that of atrial septal defect, and is widely transmitted to all parts of the body. The murmur of atrial septal defect is between the 2nd and 3rd ribs on the left, and is softer and more localized. The murmur of patent ductus arteriosus is higher, between the 2nd ribs, and is loud, coarse, and widely transmitted. It is continuous and sounds like a machine turning, and can be heard during both systole and diastole. The murmur of tetralogy of Fallot varies in position and loudness depending on the deformity, and the murmur in severe cases is actually lighter.
