Five-Chambered Heart With Double-Chambered Left Ventricle Diagnosed by Multimodality Imaging
Double-chambered left ventricle, or bifid cardiac apex, is a rare cardiac anomaly in which the left ventricular chamber is divided in 2 by a muscular band or septum, and its true incidence is unknown.1 It is usually incidentally discovered, and its clinical significance is uncertain. It may be associated with other congenital anomalies.2 It is important to distinguish double-chambered left ventricles and diverticula from other left ventricular outpouchings, such as aneurysms or pseudoaneurysms, as they have important prognostic implications.
