Ancillary Study:

Left Ventricular Dysfunction is Associated with Intraventricular Dyssynchrony by 3-Dimensional Echocardiography in Children (PDF), G. Baker, JASE 2008; 21(3):230-233.

“Dyssynchrony” means that parts of the heart do not squeeze at the same time. This causes less efficient ejection of blood and contributes to heart failure. There is little data on dyssynchrony in children. This small study looked at whether 3-dimensional echocardiography (heart ultrasound) can be used to identify dyssynchrony in healthy children and children with poor heart function.  The results show that 3D echocardiography can be used to look at dyssynchrony in children, and that patients with poorer heart function have more dyssynchrony.
