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… CONTINUE READING
