• Echocardiography during active pulmonary embolism can reveal the embolic mass in transit through the chambers of the right side of the heart. The pattern produced is that of multiple masses of varying sizes, shapes, and densities moving from the right atrium to the right ventricle. It was not present on repeated echocardiogram performed several weeks later, after anticoagulation treatment. Proper recognition of this pattern can lead to prompt medical treatment with anticoagulants, which, in this case, led to a quite satisfactory clinical outcome.
