Cardiac tamponade occurs when fluid builds up between the heart muscle and the surrounding tissue called the pericardium. This fluid compresses the heart. Because of this, enough blood cannot be pumped in and out of the heart.
This condition can be life-threatening. Cardiac tamponade can be treated, but it can return after treatment.

Cardiac tamponade can be caused by a variety of factors and conditions, including:
- Pericarditis —an inflammation of the sac that surrounds the heart, caused by bacterial or viral infections
- Bleeding into the pericardium, caused by injury
- Ruptured heart muscle
- Cancer in or near the heart
