Overview
Pericardial effusion secondary to pericarditis is seen on echocardiogram as a large hypoechoic region surrounding the heart. A swinging motion of the heart with each beat may also be noted in the setting of cardiac tamponade. It is this swinging motion that gives rise to electrical alternans. Echocardiography demonstrates the collection of pericardial fluid. The best view to visualize a pericardial effusion is the subcostal view. Signs of more advanced tamponade include indentation of the atrium and ventricle, and in later stages collapse of these structures. The location of the fluid should be characterized so that the feasability and safety of pericardiocentesis can be assessed. For example, the location of the fluid should be characterized as either circumferential, posterior or anterior. The cm of fluid thickness should be characterized. The presence of loculations should be described. Usually pericardiocentesis can be performed if there is over 0.5 cm of anterior fluid.
Pericardial effusion and cardiac tamponade
In pericardial effusion, large hypoechoic regions are seen surrounding the heart with presence of oscillatory motion of heart.
