An X-ray of the chest shows heart enlargement. During heart catheterization , a definitive diagnosis is made by showing the abnormal appearance of the blood vessels. An echocardiogram shows a VSD and a single truncal artery. Surgery is needed to treat this condition. Complete repair appears to be the preferred option but as the child grows repeat surgical procedures may be necessary.
Complete repair can produce good results.
Untreated cases have a poor outcome. Call for an appointment with your health care provider if your infant or child appears lethargic , does not eat well, appears excessively tired or mildly short of breath, or does not seem to be growing or developing normally.
