Pulmonary hypertension composite score of echocardiographic measures

Subjective quantification of RV pressures	Absolute criteria	Supportive criteria
Subjective quantification of RV pressures	Septal geometry in systole	Shunting^a	RV function^b	RV / RA size^c
Normal (< 1/3 systemic)	Septum round Eccentricity index^d ≤ 1.0	L to R	Normal	Normal
Mildly elevated (1/3–2/3 systemic)	Septal geometry mildly distorted, Eccentricity index 1.01–1.20	L to R	Normal	Mildly dilated
Moderately elevated (≥ 2/3 systemic)	Septum moderately distorted but not flat, Eccentricity index 1.21–1.4	L to R	Mildly depressed	Mod. dilated
Severely elevated (≥ systemic)	Septum flat or bowing into left ventricle, Eccentricity index > 1.4	R to L	≥Moderately depressed	Severely dilated

RV – right ventricle; RA – right atrium; L – left; R – right

^a.

Across a PFO/ASD or PDA

^b.

Measures of RV function to include: subjective estimates, RV fractional area change, tricuspid annular plane systolic excursion

^c.

RV/RA size based on subjective appearance

^d.

LV eccentricity index (LVEI) = LV antero-posterior diameter / LV septo-lateral diameter
