Prenatal diagnosis: Hypoplastic left heart syndrome in combination with ventriculo-coronary communication.

BACKGROUND

Both hypoplastic left heart syndrome and ventriculo-coronary communication are extremely rare congenital cardiac conditions.

CASE: The diagnosis of hypoplastic left heart syndrome combined with endocardial fibroelastosis and ventriculo-coronary communication was made in a pregnant woman at 24 weeks of gestation. Interestingly, unlike diastolic flow from the coronary artery to the left ventricle in typical ventriculo-coronary communication, this fetus showed a systolic flow from the left ventricle to the coronary artery.

CONCLUSION

To the best of our knowledge, this is the first study to present only a systolic flow signal in hypoplastic left heart syndrome combined with ventriculo-coronary communication in prenatal ultrasonography.
