Creation of high position fetal balloon atrial septoplasty for hypoplastic left heart syndrome and highly restrictive atrial septum: A case report and literature review.

BACKGROUND

Fetal balloon atrial septoplasty (BAS) is performed through the restrictive foramen ovale in fetal cases with established hypoplastic left heart syndrome (HLHS) and an intact or highly restrictive atrial septum (RAS).

METHODS

In the current report, we present a case of high position BAS in a fetus with HLHS/RAS.

RESULTS

Echocardiography confirmed an adequate atrial opening above the foramen ovale and fetal pleural effusion resolved spontaneously 1 day after the procedure.

CONCLUSION

To the best of our knowledge, the creation of a high position hole in the thinner part of the atrial septum, instead of the restrictive tiny hole, has not been reported in fetal cases with HLHS/RAS.
