When the intrapericardial pressure becomes high enough to impede cardiac filling, cardiac function becomes impaired, and cardiac tamponade can be considered to be present. (See Cardiac tamponade.) A general overview of the diagnosis and treatment of pericardial effusion will be presented here. The full spectrum of causes of pericardial disease, management of specific causes of pericardial disease, and the details of pericardial fluid drainage are discussed separately.
