Diagnosis and follow-up of congenital heart disease in children with the use of two-dimensional Doppler echocardiography

Abstract

Two-dimensional echocardiography (2D) represents a major advance in non-invasive diagnosis of congenital heart disease (CHD) in children. Nevertheless it has diagnostic limitations in nearly all kinds of heart lesions. These can be overcome for the most part by integration of a pulsed Doppler system. This may be called two-dimensional Doppler echocardiography (2DD). Hereby blood flow information is added to the 2D image. Some common types of CHD including ventricular and atrial septal defects, persistent ductus arteriosus, pulmonic stenosis and coarctation are described with their typical 2DD findings. Non-invasive follow up of children with CHD and early recognition of typical complications can be achieved reliably using 2DD. Future prospects consist in a more quantitative diagnostic application of 2DD.
