Prenatally Diagnosed Right Ventricular Outpouchings: A Case Series and Review of the Literature

Congenital right ventricular aneurysms and right ventricular diverticula are rare forms of congenital heart disease for which little information exists regarding optimal management, natural history, or prognosis. With advancements in prenatal cardiac evaluation and ultrasound, the reported frequency of these lesions, as well as a better understanding of the natural history of this form of congenital heart disease, is likely to evolve. We present three cases of fetal right ventricular aneurysms/diverticula diagnosed at our institution, along with a review of the current literature. We describe the pre- and postnatal courses as well as suggest counseling and management strategies.
