Left ventricular myocardial deformation as measure of hemodynamic burden in congenital valvular aortic stenosis

Left ventricular myocardial deformation as measure of hemodynamic burden in congenital valvular aortic stenosis

Changes in 2D echocardiography (2DE) speckle tracking imaging (STI) derived left ventricular (LV) strain (S) and strain rate (SR) precedes diminution of LV ejection fraction (LVEF) in adult valvular aortic stenosis (AS). We prospectively examined whether 2DE-STI derived multidirectional LV S and SR...

Zusammenfassung:Changes in 2D echocardiography (2DE) speckle tracking imaging (STI) derived left ventricular (LV) strain (S) and strain rate (SR) precedes diminution of LV ejection fraction (LVEF) in adult valvular aortic stenosis (AS). We prospectively examined whether 2DE-STI derived multidirectional LV S and SR correlate with AS severity in children using LV mass index (MI) as the principal outcome variable. 52 children (10.4 ± 7.3 years) with isolated congenital AS were included; 13 mild (2.5 m/s
