Pericardiocentesis under two-dimensional echocardiographic guidance in loculated pericardial effusion

Pericardiocentesis to relieve tamponade from a loculated pericardial effusion in patients following cardiac surgery is greatly aided by two-dimensional echocardiographic imaging guidance. This technique delineates the fluid distribution and the site of adhesions, defines the path for introduction of an aspiration needle, alerts to the possibility of myocardial contact, and helps in positioning the drainage catheter. Two-dimensional echocardiographic imaging can be performed at the patient's bedside, and the images are easy to interpret. This technique simplifies pericardiocentesis and helps to avoid complications.
