Children with congenital heart disease

My son is 2 years old to the hospital because of a cold when found to be \\The following is the cause of congenital heart disease and bicuspid aortic valve malformations of introduction, I hope for your help. Congenital heart disease Congenital heart disease is the cause of common congenital malformations of children is one of the fetal period of the heart, blood vessels caused by developmental abnormalities, the incidence rate was 7 �� -8 �� the sick child was born severely deformed after a few weeks or months and death. Since the 50s of this century, with the rapid development of medical technology, the majority of patients after surgical treatment, may be a more healthy growth, which should be diagnosed as early as possible, clear type, and reasonable treatment, without losing the timing of surgery for the best effect. There are many reasons congenital heart disease, congenital heart disease, currently considered the main factors related to causes of the following five categories: a cause of congenital heart disease: fetal development to environmental factors in utero infection is the most important congenital heart disease reasons, among which the most prominent of rubella virus infection, followed by the Coxsackie virus infection. If the mother suffering from rubella during the first three months of pregnancy, the baby produced by high prevalence of congenital heart disease; which the patent ductus arteriosus and pulmonary valve stenosis is more. This is due to the development of fetal heart and great vessels in the eight weeks of pregnancy to form the second, but this time in utero infection can affect the fetal heart development with the rules. Other lesions, such as amniotic membrane, fetal pressure, pregnancy, threatened abortion, maternal malnutrition, diabetes, benzene ketonuria, hypercalcemia, radiation and cytotoxic drugs in the application of early pregnancy, fetal congenital heart disease are so reasons. The mother ate during pregnancy certain medications can also cause fetal cardiac malformations. Congenital heart disease two reasons: preterm premature birth is an important cause of congenital heart disease. Preterm children suffering from ventricular septal defect and patent ductus arteriosus, were more likely, the former before they are born with ventricular septal not have sufficient time to complete the development on which children with the premature contraction of blood vessels after birth is not strong enough related. 2500g birth weight in newborns, especially susceptible to the following congenital heart disease. Congenital heart disease three reasons: the low partial pressure of oxygen high altitude plateau one of the causes of congenital heart disease; highland areas of congenital heart disease - patent ductus arteriosus, atrial septal defect and congenital heart disease, more. Patients in Qinghai high disease rates than the original plain regions. Four reasons for congenital heart disease: genetic factors, genetic factors are also one of the causes of congenital heart disease. In a family, siblings or parents and children, while also suffering from congenital heart disease, and many chromosomal abnormalities in genetic diseases also have examples of cardiovascular malformations, indicating the existence of the disease have genetic factors. Genetic research suggests that most of the congenital heart disease is the interaction of multiple genes and environmental factors are formed. Five reasons for congenital heart disease: other factors, age is one of the causes of congenital heart. Old mother (35 years and over) production tetralogy of Fallot patients, the risk of Down syndrome babies more. Some congenital heart disease have significant differences in incidence between males and females. Of congenital bicuspid aortic valve malformations introduction of congenital bicuspid aortic valve abnormalities in males, left and right second leaf compared before and after the type of common, can cause aortic valve insufficiency and / or stenosis, in order to insufficiency more common (75%). Few life-long aortic insufficiency does not appear and / or stenosis. Congestive heart failure occurs, angina, syncope, infective endocarditis should be treated surgically as soon as possible. Obvious symptoms of the patients should be regularly reviewed by echocardiography. Aortic valve replacement is a commonly used surgical methods. Control the timing of surgery is the main one of the two symptoms, such as significant fatigue, syncope, angina, etc., because once the obvious symptoms, so developing very rapidly. Also, if there are no symptoms, so if there is also the case in a timely manner following surgery: left ventricular end systolic diameter> 55mm, left ventricular end diastolic diameter> 80mm, ejection fraction EF300ml. Are considering surgery. Sometimes not even achieve the above, if we find the heart to further expanding progressive decline in cardiac function, but also to consider surgery. I hope the above answer to your help. This is mostly caused by infection early pregnancy, valvular problem is too much trouble, can cause regurgitation, cardiac function over time affected the day after tomorrow are less likely to turn good, the heart of recommendations to the authority of the hospital early examination and early treatment recommended for Shanghai Children's Medical Center, I wish the baby good luck!! Hello, bicuspid aortic malformations are relatively rare congenital heart disease, heart function better if the child, usually without discomfort, as long as you can review regularly to hospital .
