As the fluid accumulates in the pericardial cavity, the normal movements of the heart wall are inhibited, leading to a condition called cardiac tamponade Pericarditis is most often caused by a viral infection. It can also develop after a heart attack or heart surgery. Most cases can be successfully treated with over the counter or prescription anti-inflammatory drugs. For severe or recurrent cases pericardiocentesis may be performed. During this procedure, a needle is inserted into the pericardial cavity to remove excess fluid.
