Bidirectional Glenn is a surgical treatment used for children who do not have two pumping chambers of the heart. This can be caused by many different diagnoses which all result in a single ventricle. These conditions include: Tricuspid atresia The bidirectional Glenn procedure directs the blood flow from the upper body veins directly to the lungs rather than the heart pumping the blood to the lungs first. The bidirectional Glenn shunt redirects blood flow from the upper body veins and is often performed prior to having a Fontan procedure.

Coarctation of the aorta is when the largest blood vessel in the body is narrowed. This narrowing makes it difficult for blood to reach the lower body. The symptoms depend on the severity of the narrowing. Newborns with a severe narrowing may be in shock with no blood flow to the legs, kidneys and intestines. If mild, older children may be diagnosed by weak leg pulses or an elevated blood pressure in their arms. Treatment The pediatric cardiac surgeons are able to enlarge a severely narrowed aorta with surgical treatment.

When the heart or blood vessels near the heart do not develop normally before birth, a condition called congenital heart disease occurs (congenital means "existing at birth"). Heart defects are the most common type of birth defect, occurring in 1 out of every 120 live births. Most are detected at birth, but sometimes they so not present symptoms until adulthood. Inova's highly specialized physicians offer care to newborns and children with congenital heart disease.

Diagnostic cardiac catheterization is a special test to collect enough information about a child's heart problem to establish a plan for care. The Inova interventional pediatric cardiologist guides a catheter to the heart.

Fontan is a surgical treatment used for children who do not have two pumping chambers of the heart. Blood coming back from the veins of the body is sent directly to the lungs, rather than the heart pumping the blood to the lungs. Most children with this condition will have had a bidirectional Glenn shunt to redirect blood flow from the upper body veins prior to having a Fontan procedure.

Philanthropy has empowered our program to grow with an increase in cardiac surgical procedures, advancements in our fetal heart program, the creation of a dedicated electrophysiology program and ongoing growth of our adult congenital heart program, in collaboration with the Inova Heart and Vascular Institute. Inova relies on community support to provide excellent care close to home.

Heterotaxy syndrome is a rare birth defect involving the heart and other internal organs. “Hetero” means different and” taxy” mean arrangement – so the organs have a different arrangement. It is seen in boys and girls equally and can occur in all ethnic groups. Four babies in one million are born with this problem. In heterotaxy syndrome, paired organs like the lungs or kidney are often mirror images of each other instead of having the features of right and left that normally occur.

Children with congenital heart disease may benefit from one of the medically advanced, minimally invasive procedures performed in one of our dedicated pediatric cardiac catheterization labs. Our specialists use catheters, balloons and coils designed uniquely for children and infants to open or dilate narrowed blood vessels and heart valves. Cardiac catheterization procedures may also be used to close areas where blood is not supposed to flow.

Kawasaki disease is a condition that causes high fever and inflammation of the mouth, hands, feet and other areas of the body. The disease causes some of the body’s arteries to become inflamed, including the arteries that feed the heart (coronary arteries). Children with Kawasaki disease are treated with IV immunoglobulin. Even if treated, Kawasaki disease can cause the coronary arteries to enlarge and form aneurysms. An aneurysm is a weak area that tends to pouch out like a balloon. The enlarged vessel allows blood to sit still which can cause a blood clot to form in the coronary artery.
