Classification of Congenital Heart Disease



Congenital Heart Disease

Classification of Congenital Heart Disease

There exist different classification systems of congenital heart defects. It was in the year 2000 when an international congenital heart naming was founded to offer a generic system of classification. In this case, various congenital defects were discovered and these include:

Hypoplasia: when one suffers from this kind of heart complication, the affected heart results to the right or left ventricle to under develop. This therefore leaves only one capable side of the heart to effectively pump blood to the entire body as well as the lungs. This is not a common heart condition but it is believed to be the most grievous type of the congenital heart disease. When it affects the left ventricle, it is referred to as hypoplastic left heart syndrome and vice-versa if it affects the right ventricle. In all cases, for the infant to survive until surgery is performed, patent ductus arteriosus is very important. The pathways ensure that blood circulates to the whole body. It is sometimes referred to as cyanotic heart defect.

Obstruction defects: this condition occurs when the valves, veins and arteries of the heart become abnormally narrow or blocked. The most common defects are aortic stenosis, coarctation of the aorta and pulmonic stenosis, while the bicuspid aortic valve stenosis and sabaortic are rare cases.

Septal defects: In this case, the septum separates the left from the right heart and in the event of defective occurrence in the intraventricular septum or the interatrial septum, will cause blood to flow from left to the right affecting the efficiency of the heart.

Cyanotic defects: This derives their name due to the results of cyanosis, a bluish grey skin discoloration caused by deficiency in oxygen in the blood.
