Congenital heart disease

Congenital cardiovascular disease is a congenital malformation of the most common category. With cardiac diagnosis and surgical treatment of technological progress, An overwhelming majority of congenital cardiovascular disease can be clear in the diagnosis and treatment of surgical correction. Prognosis more significantly changed. [Due to cause fetal cardiac development in the process of being interfered with, or halt the development of defects The degradation and some were not entirely due to degradation. 1, fetal environmental factors around the early intrauterine pregnancy infection to rubella virus infection disappearing often caused patent ductus arteriosus and pulmonary stenosis. followed by the Coxsackie virus infection (Coxsackie) can cause endocardial fibroelastosis. In addition amniotic membrane disease, fetal around machinery of oppression, the mother Nutrition disorders, vitamin deficiency and metabolic diseases, mother with cytotoxic drugs or irradiation longer, and may be related to the jaw section due. 2, 5% of genetic factors in patients with congenital heart disease occurred in the same family, the disease the same or similar. Since abnormal gene may or chromosomal aberrations induced. Three other highland areas of patent ductus arteriosus and atrial septal defect with high incidence of occurrence may be related to hypoxia. Some congenital heart disease gender bias. [Classification -- under hemodynamics with pathophysiological changes can be made for three categories : one, no triage category left, Right side without segregation, without cyanosis, pulmonary stenosis, aortic stenosis, coarctation of the aorta, primary pulmonary expansion Primary pulmonary hypertension and right heart, and other places. 2, left to right shunt type of the left and right ventricular cavity or main pulmonary abnormal channel between the left than the right pressure, Abnormal blood through the left channel to the right vein -- left-to-right shunt, such as atrial septal defect, ventricular septal defects, patent ductus arteriosus, and the main pulmonary artery septal defect, some anomalous pulmonary venous drainage, Valsalva (Valsalva) sinus aneurysm ruptured into the right ventricle. General without cyanosis, if in advanced pulmonary hypertension occurred, a two-way or right to left shunt, appeared cyanotic, known as the Advanced cyanotic. 3, the right-to-left shunt type of right heart or pulmonary artery pressure increased abnormally, abnormal blood flow through the channel into the left ventricular cavity or aorta. General soon after birth that is, cyanosis, as Fallot's tetralogy, France's Le triple syndrome, tricuspid atresia, truncus arteriosus in, macrovascular take place Eisenmenger's Syndrome (Eisenmenger 's syndrome). [Typical common diagnosis -- congenital heart disease, symptoms, signs, ECG, X-ray and echocardiography in diagnosis can be made. and to estimate the hemodynamic changes in the scope and severity to determine treatment programs. Other malformations of the merger, complex congenital heart disease, cardiac catheterization with or angiographic examinations, understand their abnormal lesions, type and scope of the overall analysis, a clear diagnosis, and to develop treatment programs.Prognosis -- usually depends on the type of malformation and magnitude suitable for surgery to correct the timing of surgery and preoperative cardiac function, complications involved. No triage category or left to right shunt type, to a lesser extent, asymptomatic, ECG and X-ray was normal, and, Severe corrective surgery can be adopted, the better the prognosis, if so severe pulmonary hypertension is a two-way streaming poor prognosis. right-to-left shunt or composite deformities, to more severe disease, should undergo early surgery. Light will have a choice of timing of surgery, to around 10-year-old is better. Congenital heart disease ventricular septal defects, patent ductus arteriosus and France Tetralogy of Fallot with more infectious endocarditis. prognosis, the need to maintain control.
