BACKGROUND: Congenital heart defects such as coarctation or valvular aortic stenosis are
followed by changes in left ventricular myocardial deformation mechanics induced by
pressure overload. METHODS: Echocardiography was performed in 37 patients (aged 0-27
years, 15 female) with coarctation (27) or valvular aortic stenosis (10) before and after
interventional catheterization and compared with 37 body surface area/age-matched healthy
children. Deformation was calculated by 2-dimensional strain speckle tracking. RESULTS …
