Figure 2: The typical echocardiography signs seen in a patient of acute pulmonary embolism (PE) are described. (a) Dilated right atrium and right ventricle with moderate tricuspid regurgitation (TR) jet on color flow. (b) Right ventricular systolic pressure (RVSP) of 36 mmHg derived from TR jet velocity signal using continuous-wave Doppler. (c) Pulsed-wave Doppler across pulmonary valve to calculate pulmonary acceleration time (52 ms) and 60/60 sign which is a combination of RVSP <60 mmHg and pulmonary acceleration time <60 ms with mid-systolic notch, a highly specific sign for acute PE. (d) Basal right ventricular:left ventricular ratio is >1 with dilated right ventricle. Basal right ventricular diameter is 38 mm, measured 1 cm below the tricuspid annulus. (e and f) Calculation of right ventricular fractional area change by tracing right ventricular endocardium in diastole and systole, respectively, right ventricular fractional area change in this case was 23% suggesting moderate right ventricular systolic dysfunction
