Aortic stenosis occurs when the aortic valve is unable to open completely. Learn about the tests used to diagnose this condition and how it is treated.

An atrial septal defect is an opening in the wall between the two atria of the heart. Learn about the different types, and how they are diagnosed and treated.

Learn about atrioventricular septal defect and how it is diagnosed. This condition occurs when the atria and ventricles have not separated properly and also the mitral and tricuspid valves have not separated.

A bicuspid aortic valve occurs when there are two instead of three leaflets in the aortic valve. Find out more about the condition and how it is diagnosed.

With cardiomyopathy the muscle of the heart is affected and is no longer able to pump effectively. Find information on the different types of cardiomyopathy and how it is treated.

Find out about coarctation of the aorta and how it is diagnosed. This condition occurs when there is a narrowing of the major artery leading away from the heart.

Interrupted aortic arch occurs when the aorta does not develop properly. Learn more about how this condition is diagnose and how it is treated with surgery.

Learn about mitral valve prolapse and how it is diagnosed. The condition occurs when the leaflets of the valve bulge back into the left atrium of the heart.

Patent ductus arteriosus happens when the opening between the aorta and the pulmonary artery that is present before birth does not close. Learn how this condition is diagnosed and treated.

Learn about pulmonary atresia where there is no opening from the right ventricle of the heart into the pulmonary artery. Read about some of the tests and procedures used to diagnose and treat the condition.

Pulmonary stenosis occurs when the pulmonary valve is unable to open completely. Learn about the tests used to diagnose this condition and how it is treated.

Tetrology of Fallot is a condition made up of four heart defects. Learn how this condition is diagnosed and what is does to treat it.

Total anomalous pulmonary venous return occurs when the vessels returning blood to the heart from the lungs are not connected correctly. Learn how this condition is diagnosed and how it is treated with surgery.

Learn about tricuspid atresia where there is no opening between the right atrium and the right ventricle of the heart. Read about some of the tests and procedures used to diagnose and treat the condition.

Learn about truncus arteriosus where there is only a single artery coming out of the ventricles instead of the pulmonary artery and the aorta. Read about some of the tests and procedures used to diagnose and treat this condition.

An ventricular septal defect is an opening in the wall between the two ventricles of the heart. Learn about the different types, and how they are diagnosed and treated.

Learn about other types of rare congenital heart conditions such as dextrocardia, single ventricle anomalies and vascular ring.
