Every child is a beautiful angel, and the greatest wish of all parents is that their children grow up healthy. But sometimes it is often not what you want, some children are born as angels with broken wings. Therefore, parents should not underestimate every aspect of their children’s growth process. Congenital heart disease, congenital heart disease, is a common type of congenital malformation, accounting for about 28% of all congenital malformations, refers to anatomical abnormalities caused by the formation of heart and large blood vessels during embryonic development or abnormal development. A small percentage of congenital heart disease has a chance of self-healing before the age of 5. In addition, a small percentage of patients have mild malformations that do not significantly affect circulatory function and do not require any treatment, but most patients require surgical treatment to correct the malformations. With the rapid development of medical technology, the effect of surgery has been greatly improved. At present, most patients can recover as normal as normal people if they are treated with surgery in time, and their growth and development will not be affected, and they will be able to perform their ordinary work, study and life needs. So for parents who find their children abnormal please go to the hospital in time to check, this plays a big role in the child’s subsequent healthy growth and even life path. For congenital heart disease parents need to take their children to do the following tests: 1. ECG By doing ECG examination, congenital heart disease can be screened, and can be indirectly determined according to the voltage changes in one or several chambers of the heart hypertrophy increased, and can also be found in patients with congenital heart disease accompanied by abnormalities in the electrical conduction path, equivalent to your home laid the wrong wires, placed the wrong appliances. Therefore, the use of ECG in combination with other imaging tests can accurately determine the diagnosis of heart disease. ECG is a fairly good adjunctive test to determine congenital heart disease. It is important to note that a normal ECG does not expel congenital heart disease. It is equivalent to being in your house renovation, the circuit is right, you cannot be completely sure that there is a hole in the wall of the house, the door gap is too wide, etc. 2. Chest X-ray If you suspect the presence of heart disease in a newborn, you can go for a chest X-ray. Usually, egg-shaped heart indicates transposition of the great arteries, and boot-shaped heart indicates tetralogy of Fallot. 3.Echocardiogram Echocardiogram is a non-invasive test that allows real-time dynamic observation of abnormalities in heart structure and blood flow. It includes M-mode ultrasound, two-dimensional ultrasound, color Doppler ultrasound, and three-dimensional ultrasound. It is the most valuable diagnostic method for heart disease in the neonatal period. For newborns, it can diagnose various heart, large blood vessels and coronary artery malformations, and determine cardiac function and pulmonary artery pressure because of the clear images displayed, and can also be used to dynamically observe cardiac changes, which is important for determining the degree of cardiac lesions in children, monitoring treatment and assessing prognosis. 4, cardiac magnetic resonance imaging The good temporal and spatial resolution of magnetic resonance has the ability to simultaneously display the structure and function of the heart, coupled with the absence of radiation damage, so this non-invasive test, which integrates morphological, functional and cell biological examination, has developed into an ideal method for the diagnosis and differential diagnosis of heart disease, and is considered the “gold standard” for determining the heart and functional structure. It is considered the “gold standard” for determining the heart and its functional structure. 5, cardiac catheterization and cardiovascular imaging Cardiac catheterization helps to clarify the diagnosis of congenital heart disease and can provide accurate hemodynamic information; cardiovascular imaging improves the rate of confirming the diagnosis of congenital heart disease, especially complex congenital heart disease and can provide a reliable basis for surgical correction of malformations. In recent years, echocardiography has replaced cardiac catheterization and cardiovascular angiography in the diagnosis of some congenital heart diseases, such as common ventricular septal defect, atrial septal defect, and patent ductus arteriosus. However, in the diagnosis of certain congenital heart diseases or complex congenital heart diseases, the doctor is required to make a more accurate diagnosis in order to provide a basis for surgery, and in this case, cardiac catheterization and cardiovascular angiography must be performed to further clarify the heart malformations and various physiological indicators. Currently, cardiac catheterization and cardiovascular imaging are more often used for therapeutic purposes, such as early neonatal atrial septal fistula and arterial catheter occlusion.
