WHAT YOU NEED TO KNOW:
Pericardial effusion is a buildup of fluid in the pericardium. The pericardium is a 2-layer sac that surrounds the heart. The sac normally contains a small amount of clear fluid between its layers. This allows the heart to move smoothly against other organs in the chest as it beats. The buildup of fluid may affect how the heart works.
