Aortic valve regurgitation

In aortic valve regurgitation, the aortic valve doesn't close tightly, causing blood to leak back into your heart.

Aortic valve stenosis

In aortic valve stenosis, the aortic valve narrows, blocking blood flow. The aortic valve connects your heart to the aorta, your body's main artery.

Atrial septal defect

Atrial septal defect (ASD) is an abnormal opening between the heart's upper pumping chambers. It's common and readily treated.

Atrioventricular canal defect

Atrioventricular canal defect is a congenital heart defect involving a hole in the center of the heart and abnormal valves between the heart's chambers.

Cardiogenic shock

Cardiogenic shock is a life-threatening complication usually of a heart attack. Cardiogenic shock treatments can be effective, but must be provided immediately.

Cardiomyopathy

Cardiomyopathy is a heart muscle disease. Treatment options depend on what type of cardiomyopathy you have.

Chest pain

Chest pain can be frightening, but it doesn't always indicate a heart attack.

Coarctation of the aorta

Coarctation of the aorta is a cardiovascular defect resulting in a narrowing of the aorta, the blood vessel that delivers oxygen-rich blood to your body.

Dilated cardiomyopathy

Ebstein's anomaly

Ebstein's anomaly is a rare heart defect. Some people may not have any symptoms, but others may need treatment, including surgery.

Eisenmenger syndrome

Eisenmenger syndrome, a complication of congenital heart defects, can be life-threatening if not properly treated. Find out more.

Enlarged heart

Enlarged heart is often a sign of a serious heart condition. Find out causes and treatments for enlarged heart.

Heart attack

Heart disease

Heart disease, usually thought of as blockages in the arteries that can cause a heart attack, can describe any medical condition affecting your heart.

Heart failure

Heart failure means your heart can't efficiently pump blood throughout your body. Medications, and sometimes devices or surgery, can help you manage this condition.

Heart murmurs

This whooshing sound in your heart is usually harmless, but in some cases heart murmurs can alert your doctor to specific heart conditions.

Hypertrophic cardiomyopathy

Hypertrophic cardiomyopathy is a genetic disorder in which heart muscle becomes abnormally thick. It's the most common cause of sudden cardiac death in young people.

Mitral valve prolapse

Mitral valve prolapse occurs when the valve separating two of your heart's chambers malfunctions. The disorder usually isn't serious and often doesn't require surgical treatment.

Mitral valve regurgitation

Mitral valve regurgitation occurs when blood flows backward in your heart because the mitral valve closes improperly.

Mitral valve stenosis

In mitral valve stenosis, the mitral valve is narrowed, obstructing blood flow between the chambers on the left side of the heart.

Myocarditis

Myocarditis is a disease in which the heart muscle becomes inflamed and swollen, often as the result of an infection.

Patent ductus arteriosus (PDA)

Patent ductus arteriosus (PDA) is a persistent, abnormal opening between the aorta and pulmonary artery. If it doesn't resolve on its own, it's readily treated.

Patent foramen ovale

Patent foramen ovale, an opening between the heart's upper chambers, usually doesn't require treatment.

Pulmonary atresia

Pulmonary atresia is a heart defect that you're born with. Fortunately, treatment soon after birth and ongoing throughout childhood and adulthood greatly improve your prognosis.

Pulmonary hypertension

High blood pressure affecting only the arteries in your lungs is known as pulmonary hypertension. Discover the symptoms, risk factors and treatment for this condition.

Pulmonary valve stenosis

Pulmonary valve stenosis is a narrowing of the valve that controls blood flow from your heart to your lungs. It's usually present at birth.

Spontaneous coronary artery dissection

Find out about this rare cause of heart attack in young, healthy people.

Tetralogy of Fallot

Tetralogy of Fallot, a cause of "blue baby" syndrome, is a congenital heart condition resulting in oxygen-poor blood leaving the heart and entering the body.

Transposition of the great arteries

Transposition of the great arteries is a congenital heart defect in which the placement of the aorta and the pulmonary artery is switched.

Ventricular septal defect

A ventricular septal defect (VSD) is an abnormal opening between the heart's lower chambers. Untreated, this congenital defect may cause heart failure and pulmonary hypertension.
