Discussion and conclusion
It is very unusual to visualize a pulmonary artery thrombus on transthoracic echocardiography (TTE). This is the first case of a visualized pulmonary arterial thrombus in an intermediate-risk APE patient by transthoracic echocardiography. In this case report we demonstrate how transthoracic echocardiography permits to obtaining a new view, which allows real visualization of the moving thrombosis during the cardiac cycle. First, two dimensional echocardiograms of the parasternal long axis view were obtained. The right pulmonary artery view was obtained by placing the transducer inclination 30-45 degree to the chest wall at the second intercostal space immediately to the right of the sternum (Figure3). Thus, we propose the new transthoracic echocardiography view as the tool of choice to evaluate the change of the thrombosis and treatment effect.
