Children with congestive heart failure causes

The etiology of heart failure caused many children, During heart failure in children within a 1-year-old the highest incidence rates, particularly in the areas of congenital heart disease were the most common cause, endocardial fibroelastosis, dilated cardiomyopathy, congenital heart disease is also an important reason. The reasons for the often-induced heart failure for bronchial pneumonia, severe anemia, electrolyte disturbance and hypoxia, etc..
According hemodynamics and pathophysiological changes in heart failure can be broadly divided into:
1, muscle contraction dysfunction (cardiac failure): heart failure due to various reasons including the myocarditis, dilated cardiomyopathy, endocardial fibroelastosis, Kawasaki disease, etc.;
2, Room overloading, is divided into: ventricular overload before (volume overload), including left-to-right shunt type of congenital heart disease, valvular regurgitation of the disease, such as infusion too much too fast; ventricular afterload heavy (pressure overload), including aortic stenosis, pulmonary valve stenosis, coarctation of the aorta, pulmonary valve atresia; 3, Room filling obstacles include: narrow pericarditis, pericardial tamponade, restrictive or hypertrophic cardiomyopathy, and so on.
