EAE Guidelines for the Assessment of Right Ventricle

Parasternal short-axis views at the mid-ventricular level illustrating measurements of left ventricular diameters for calculation of the eccentricity index (EccIx). (A) Normal heart with diastolic EccIx = 1. (B) Patient with pulmonary hypertension with diastolic EccIx = 1.8. Legend: LVAP, LV antero-posterior diameter; LVSL, LV septo-lateral diameter.
