Echocardiography
Most important clinical test
High detection rate for<unk> 
Allows operator to visualize the defect and assess how much bloodflow is crossing the defect by using color flow Doppler
Allows for detection of other possible structural defects
Often used to follow<unk> s for spontaneous closure
EKG
Most patients with have normal EKGs
Large defects may produce conduction delays or RBBB
CXR
Usually normal
May show cardiomegaly with enlarged left ventricle and atrium
May show signs of CHF
