Figure 1. Left ventricular shape in pulmonary hypertension.

Figure 1.

Eccentricity index, the ratio of the diameters (from compact myocardium) parallel (D1) and perpendicular (D2) to the ventricular septum, as measured at end-diastole (A, value 1.27), end-systole (B, value 1.53), and maximum septal displacement (C, value 1.97). Right:left ventricular diameter ratio at end-diastole (D) and end-systole (E). Maximal (and end-systolic) eccentricity index in control patient (F, value 1.03).
