FIGURE 1. Quantitative Measures of RV Dilation and Function on Conventional TTE.

FIGURE 1

(A) RVOT measurement from the parasternal long-axis view. (B) RVOT measurement from the parasternal short-axis view. RV FAC measurements should be taken from the apical 4-chamber view at end diastole (C) and end systole (D). FAC is calculated from the formula: FAC = ([RV EDA − RV ESA]/RV EDA) · 100). AoV = aortic valve; EDA = end-diastolic area; ESA = end-systolic area; FAC = fractional area change; LA = left atrium; LV = left ventricle; RA = right atrium; RV = right ventricle; RVOT = right ventricular outflow tract; TTE = transthoracic echocardiography.
