Right sided heart disease is a condition in which the right side of the heart loses its ability to pump blood efficiently.

This heart disease occurs in about 1 in 20 people. Coronary artery disease is the most common cause of heart failure in the United States, but it can be a complication of other conditions.

Heart failure may affect either sides of the heart or both. Right-sided heart failure is when the right ventricle loses its pumping function, and blood may back up into other areas of the body, producing congestion.

The congestion affects the liver, the gastrointestinal tract, and the limbs.

Causes of right-sided heart failure include complete heart failure and lung diseases. These lungs diseases are chronic bronchitis and emphysema. Other causes include congenital heart disease, clots in pulmonary arteries, pulmonary hypertension, and heart valve disease.
