Types of Congenital Heart Disease
Though there are many different types of congenital heart defects, they can be divided into three main categories:
In heart valve defects, the valves inside the heart that direct blood flow may close up or leak. This interferes with the heart’s ability to pump blood correctly.
In heart wall defects, the natural walls that exist between the left and right sides and the upper and lower chambers of the heart may not develop correctly, causing blood to back up into the heart or to build up in places where it doesn’t belong. The defect puts pressure on the heart to work harder, which may result in high blood pressure.
In blood vessel defects, the arteries and veins that carry blood to the heart and back out to the body may not function correctly. This can reduce or block blood flow, leading to various health complications.
