Hemopericardium refers to blood in the pericardial sac of the heart. It is clinically similar to a pericardial effusion and depending on the volume and rapidity with which it develops may cause cardiac tamponade.The condition can be caused by full-thickness necrosis (death) of the myocardium (heart muscle) after myocardial infarction as well as trauma and in patients receiving anticoagulants. Other causes include ruptured aneurysm of sinus of Valsalva and other aneurysms of the aortic arch.
