2D transthoracic echocardiogram (TTE) from the parasternal long axis window showing both pericardial and pleural effusions

2D transthoracic echocardiogram (TTE) from the parasternal long axis window showing both pericardial (◊) and pleural effusions (asterisk). The pericardial stripe runs anterior to the descending thoracic aorta (shown in cross section posterior to the LA), allowing differentiation between pericardial fluid and the pleural effusion, which is seen posterior to the aorta.
