Risk factorsĬongenital heart defects, such as Ebstein anomaly, occur as the baby's heart develops in the mother's womb.ĭoctors aren't sure what risk factors are associated with the defect. The heart valves, which keep blood flowing in the right direction, are gates at the chamber openings. The lower chambers, the more muscular right and left ventricles, pump blood out of the heart. The upper chambers, the right and left atria, receive incoming blood. People with WPW syndrome have an abnormal electrical pathway in the heart that can lead to fast heart rates and fainting spells.Ī typical heart has two upper and two lower chambers. Sometimes, a very fast heart rhythm causes fainting spells (syncope). An abnormal heart rhythm or rapid heartbeats make it difficult for the heart to work properly, especially when the tricuspid valve is leaking severely.

These holes can decrease the amount of oxygen available in your blood, causing a bluish discoloration of the lips and skin (cyanosis). It can remain open in some people without causing issues. A PFO is a hole between the upper heart chambers that all babies have before birth that usually closes after birth. Many people with Ebstein anomaly have a hole between the two upper chambers of the heart called an atrial septal defect or an opening called a patent foramen ovale (PFO). Other heart conditions associated with Ebstein anomalyĬommon associated heart conditions include: Some people have a mildly abnormal valve. The location of the valve and how poorly it's formed varies from person to person. This can lead to blood leaking backward into the right atrium (tricuspid valve regurgitation). This makes it so that a portion of the right ventricle becomes part of the right atrium, causing the right atrium to enlarge and not work properly.Īlso, the tricuspid valve's leaflets are abnormally formed.
In Ebstein anomaly, the tricuspid valve sits lower than normal in the right ventricle. The tricuspid valve normally sits between the two right heart chambers (right atrium and right ventricle). On the other side of your heart, oxygen-rich blood from your lungs flows into the left atrium, through the mitral valve and into the left ventricle, which then pumps the blood to the rest of your body. Blood then flows through the tricuspid valve into the right ventricle, which pumps the blood to your lungs. Oxygen-poor blood from your body flows into the right atrium. A closed valve prevents blood from flowing to the next chamber or from returning to the previous chamber. Each valve consists of two or three strong, thin flaps (leaflets) of tissue. The two lower chambers (ventricles) pump blood.įour valves open and close to let blood flow in one direction through the heart. The two upper chambers (atria) receive blood. To understand how Ebstein anomaly affects your heart, it helps to know how the heart works to supply your body with blood. Ebstein anomaly is a heart defect that you have at birth (congenital).
