- •
The objective of this study was to compare echocardiographic measures of contractility with those derived from PVL analysis in children.
- •
Noninvasive estimations of Ees correlate well with invasive gold-standard methods in children with biventricular circulation and relatively normal loading conditions.
- •
The use of these noninvasive estimates of Ees in accurately assessing LV contractility appears promising and merits further study in children.
