Is Two-Dimensional Global Longitudinal Strain Rate a preload-independent index of systemic right ventricular contractility in patients with hypoplastic left heart syndrome after Fontan operation?
Two-Dimensional Global Longitudinal Strain Rate is a preload-independent surrogate of systemic right ventricular contractility that may be useful for monitoring hypoplastic left heart syndrome patients after Fontan palliation.
In contrast to S, SR was not affected by preload and correlated with Ees of the systemic RV. SR may be a useful noninvasive surrogate of RV contractility and suitable for follow-up of patients with hypoplastic left heart syndrome after Fontan palliation.
Schlangen et al. (Wed,) studied this question.
