OP-12 Comparative case reports of prenatally diagnosed left ventricular aneurysm and diverticulum

 Objective

Primary congenital ventricular aneurysm (VA) and ventricular diverticulum (VD) are rare congenital cardiac malformations. The differencial diagnosis is based on anatomical, histological and functional criteria. In this case report; prenatal diagnosis, follow up and clinical outcomes of VA and VD is discussed.

Case

Two cases at 36 and 33 th gestational weeks were referred to our clinic due to suspected fetal cardiac anomaly.

Discussion

Clinical outcomes of VA and VD range from fetal death to asymptomatic survival. Earlier gestational week at diagnosis, outpouching related with LV and hydrops fetalis were reported as the factors associated with mortality, while the type of ventricular outpouching was not. Approximately 70% of cases remain asymptomatic in postnatal follow-up.

Conclusion

Venticular diverticulum and aneurysms should both be closely followed up prenatally.
