 There are many children that have heart dysfunction because they are either born with Congenital Heart Disease CHD or developed poor heart function because their hearts are ill. The invention of medical technology helps in the treatment of these children. New heart echocardiogram echo techniques including Tissue Doppler TDI, Tissue Synchronization Imaging TSI and 3 dimensional echocardiography 3D are imaging technologies that we hope will help in the diagnosis and treatment of these children.
