Fact Sheets

Atrial Fibrillation
Atrial fibrillation is a heart rhythm problem that causes irregular heartbeat (arrhythmia) and abnormal blood flow.
Atrioventricular Septal Defect
A congenital heart defect characterized by holes in the heart where there are normally walls that separate different heart chambers, as well as abnormal heart valves that leak.
Atrial Septal Defect (ASD)
An atrial septal defect is a hole in the wall that divides the two chambers of the heart. Learn about symptoms and treatment.
Ventricular Septal Defect (VSD)
A ventricular septal defect is a hole in the wall between the two lower chambers of the heart and is a type of congenital heart defect. Learn about symptoms and treatment.
Adult Congenital Heart Disease
Adult congenital heart disease is a type of defect in one or more structures of the heart that occurs before birth. Learn about symptoms and treatment.
Pediatric Congenital Heart Surgery
Pediatric congenital heart surgery is a procedure to correct a structural problem in a child's heart. Learn about this procedure.
Patent Ductus Arteriosus (PDA)
Patent ductus arteriosus (PDA) is a congenital heart defect that leaves a small hole in a premature baby's heart. Learn about symptoms and treatment.
Heart Murmur
A heart murmur is an extra, unexpected sound made by the blood as it flows through the heart.
Pulmonary Stenosis
A heart condition in which there is narrowing at or near the pulmonary valve. As a result, the heart must work harder than usual to pump blood to the lungs where it is oxygenated. Those with moderate to severe pulmonary stenosis may experience shortness of breath, fatigue, chest pain and other symptoms.
Tricuspid Atresia
Tricuspid atresia is a rare, life-threatening birth defect of the heart. It occurs when the tricuspid valve, one of the heart's four valves, does not form during fetal development, thereby disrupting the normal flow of blood through the heart.
