Transthoracic echocardiogram (TTE) of case 2. (A) 1.8 × 1.6 cm thrombus at the pulmonary artery bifurcation (arrow). (B) Parasternal short-axis view at mid-ventricular level showing D-shaped left ventricle (LV) in systole suggesting right ventricular (RV) pressure overload. (C) Tricuspid regurgitation velocity of 2.4 m/s; in the context of a shortened acceleration time (62 msec) suggested that there was acute pressure overload of the RV. (D) Disappearance of the thrombus after thrombolysis was demonstrated.

MPA, main pulmonary artery; RPA, right pulmonary artery; LPA, left pulmonary artery.
