Aortopulmonary windows which were successfully treated in childhood without the development of other symptoms pose no significant problems for pregnancy. However, pregnancy is dangerous for patients with extant aortopulmonary windows, with significant risks for both mothers and their unborn children.  Repaired aortopulmonary windows and pulmonary hypertension are also a high risk pregnancy.

Anyone with congenital heart disease, repaired or non-repaired, should consult with their cardiologist prior to becoming pregnant to review the risks.
