Causes

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.

Complications

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.

Endocarditis

Endocarditis is an infection of the heart's inner lining. Find out who's at risk.

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.

Pectus excavatum

Edema

Edema — swelling caused by excess fluid in tissues — can affect any part of your body. Treating the underlying cause is key to resolving edema.

Shortness of breath

Shortness of breath can be frightening. Most of the time, a heart or lung condition is the cause.

Tests and diagnosis

Cardiac catheterization

Cardiac catheterization is used as a test for some heart conditions and as a procedure to treat some types of heart disease. Find out more.

Chest X-rays

Even with today's high-tech medical devices, the basic chest X-ray remains an important tool in diagnosing various conditions. Here's a look at how it works.

CT scan

A CT scan is an imaging test that uses X-rays to produce detailed images of the inside of your body.

Electrocardiogram
