ABSTRACT
Traditional evaluation of congenital heart disease was first
performed with conventional angiography.1 While the infor-
mation enabled with catheter angiography is important in
the evaluation of patients with CHD, it remains an invasive
procedure requiring sedation and significant radiation. The
development of echocardiography enabled real time evalua-
tion with excellent anatomic detail and functional informa-
tion. It is widely available, portable and is performed without
ionizing radiation. Echocardiography has become the pri-
mary diagnostic method of choice in the evaluation of
patients with CHD.2 This technique enables non-invasive
evaluation of anatomy, myocardial and valvular function.
