Successful pregnancy and delivery in patients with uncorrected single ventricle: Three new cases and literature review.

Due to high risks of both maternal and fetal complications, pregnancy is not encouraged for women with uncorrected univentricular heart (UVH). Here, we report three cases of successful pregnancy and delivery in patients with uncorrected UVH. A literature review has been performed. It appears that maternal and neonatal risks are mainly associated with higher NYHA heart failure class, pulmonary hypertension, and history of congestive heart failure. In the absence of these risk factors, successful pregnancy still can be achieved with mild complications. Care by a multidisciplinary team during delivery is necessary to for a good prognosis.
