In case of a tamponade, fluid collects in the pericardium. As the pericardium is stiff, the heart is compressed resulting in relaxation, and thus, filling difficulties. This is a potential life-threatening situation and should be treated with pericardiocenteses, which is drainage of the fluid. Tamponade can be the results of pericarditis or myocarditis. Also, after a myocardial infarction a tamponade may develop, this is called Dresslers' Syndrome. In case of cancer, pericardial fluid may develop. This is usually caused by a Pericarditis carcinomatosa, meaning that the cancer has spread to the pericardium | |||
