A preliminary comparison of two-dimensional speckle tracking echocardiography and pressure-volume loop analysis in patients with Fontan physiology: The role of ventricular morphology.

ABSTRACT:

Objective

Speckle tracking echocardiography (STE) may be a useful modality for assessing ventricular performance in patients with single ventricle physiology. However, STE's ability to accurately assess ventricular performance in this population is unknown. The objective of this study was to perform a preliminary comparison of STE measures of myocardial deformation to reference standard measures of function derived from pressure-volume loop (PVL) analysis.

Design

This was a secondary analysis of a prospective study investigating PVLs in patients with Fontan physiology. PVLs were recorded using microconductance catheters. PVL indices included end-systolic elastance (Ees), arterial elastance (Ea), ventriculo-arterial coupling (Ea/Ees), and the isovolumic relaxation time consta
