Figure 3: Various other echocardiographic findings in acute pulmonary embolism which are reproducible and reliable for acute prognostication. (a) Tricuspid annular plane systolic excursion (15 mm) using M-mode at lateral tricuspid annulus. (b) Systolic velocity of tricuspid annulus (7 cm/s) derived by placing tissue Doppler cursor at lateral tricuspid annulus. (c) Calculation of right ventricular myocardial performance index (0.8). (d) Global longitudinal strain of right ventricle (-14%) using speckle tracking. (e) Dilated inferior vena cava (22 mm) seen in subcostal view suggesting raised right atrial pressures. (f) Inferior vena cava collapsibility is <50% calculated by placing M-mode cursor on inferior vena cava and measuring the change in inferior vena cava diameter with respiration
