CTICasesBilateral Double-Chambered Ventricles
Imaging findings
Cardiac CT and MRI show deep epicardial fat bands invaginating the right and left ventricles, dividing both into proximal and distal chambers. The tricuspid and mitral valves are normal, and a small ASD/PFO is present with dilated right atrium.
Key takeaways
Bilateral double-chambered ventricles is an extremely rare congenital cardiac anomaly where fatty or muscular bands divide both the right and left ventricles into two chambers. It must be differentiated from acquired masses or constrictive pericarditis.
