Pregnancy in a Previously Conjoined Thoracopagus Twin with a Crisscross Heart

Abstract EN

Background.

Crisscross heart (CCH) is a complex, rare, congenital, rotational, cardiac abnormality that accounts for <0.1% of congenital heart defects (CHD).

CCH is characterized by the crossing of the inflow streams of the two ventricles due to an abnormal twisting of the heart.

A case of maternal CCH has not been previously reported.

Case.

We report a case of a primigravida with a CCH, who was separated at birth from her thoracopagus conjoined twin.

Pregnancy was managed by congenital cardiology, maternal-fetal medicine, anesthesiology, and obstetrics.

She underwent a 39-week vaginal delivery without maternal or neonatal complication.

Conclusion.

A successful term pregnancy outcome was achieved in a patient with CCH using a multidisciplinary approach to address her cardiac condition.
