Prenatal diagnosis of congenital ventricular aneurysm and diverticulum: prenatal features and perinatal management

Congenital ventricular diverticulum and aneurysm are rare cardiac developmental anomalies and their pathophysiology is still unclear. They present as an anomaly of the four chambers view, cardiomegaly, arrhythmia, pericardial effusion, or hydrops. They are usually isolated anomalies. Differential diagnosis between diverticulum and aneurysm is challenging during the prenatal period. Management policy is not uniform either conservative or repeated pericardial puncture. Referral and monthly prenatal ultrasound follow‐up, birth in a tertiary center after multidisciplinary evaluation and cardiological evaluation at birth still seem mandatory.
