Congenital heart defect - corrective surgery
Congenital heart defect corrective surgery fixes or treats a heart defect that a child is born with. A baby born with one or more heart defects has congenital heart disease. Surgery is needed if the defect could harm the child’s long-term health or well-being.
Patent Ductus Arteriosus
Patent ductus arteriosus (PDA) is a heart problem that occurs soon after birth in some babies. In PDA, abnormal blood flow occurs between two of the major arteries connected to the heart.
Before birth, the two major arteries-the aorta and the pulmonary (PULL-mun-ary) artery-are connected by a blood vessel called the ductus arteriosus. This vessel is an essential part of fetal blood circulation.
Within minutes or up to a few days after birth, the vessel is supposed to close as part of the normal changes occurring in the baby’s circulation.
In some babies, however, the ductus arteriosus remains open (patent). This opening allows oxygen-rich blood from the aorta to mix with oxygen-poor blood from the pulmonary artery. This can put strain on the heart and increase blood pressure in the lung arteries.
Atrial septal defect (ASD) repair:
The atrial septum is the wall between the left and right atria (upper chambers) of the heart. A hole in that wall is called an ASD. In the presence of this defect, blood with and without oxygen can be mixed up and over time, cause medical problems and arrhythmias.
Sometimes, an ASD can be closed without open-heart surgery. First, the surgeon makes a tiny cut in the groin. Then the surgeon inserts a wire into a blood vessel that goes to the heart. Next, two small umbrella-shaped “clamshell” devices are placed on the right and left sides of the septum. These two devices are attached to each other. This closes the hole in the heart. Not all medical centers do this procedure.
Open-heart surgery may also be done to repair ASD. In this operation, the septum can be closed using stitches. Another way to cover the hole is with a patch.
Ventricular septal defect (VSD) repair:
The ventricular septum is the wall between the left and right ventricles (lower chambers) of the heart. A hole in the ventricular septum is called a VSD. This hole lets blood with oxygen mix with used blood returning to the lungs. Over time, irregular heartbeats and other heart problems can happen.
By age 1, most small VSDs close on their own. However, those VSDs that do stay open after this age may need to be closed.
Larger VSDs, such as small ones in certain parts of the ventricular septum, or ones that cause heart failure or endocarditis, (inflammation) need open-heart surgery. The hole in the septum is most often closed with a patch.
Some septal defects can be closed without surgery. The procedure involves passing a small wire into the heart and placing a small device to close the defect.
