Isolated double-chambered right ventricle in a young female – a rare congenital heart disease: Evaluation by transthoracic color echocardiography and cardiac computed tomography

Abstract

A double-chambered right ventricle (DCRV) is a rare congenital heart disease and an uncommon cause of congestive cardiac failure. An anomalous muscle band divides the right ventricle into two cavities, the proximal high-pressure chamber, and distal low-pressure
chamber. Its origin is debated. Most cases are diagnosed and treated during childhood. Furthermore, there is tendency for progression, if not treated. Echocardiography is considered useful for diagnosis. About 80–90% patients have associated congenital anomalies, such as ventricular septal defect, pulmonary stenosis, and subaortic stenosis. Isolated DCRV is exceptionally rare. Hence, we are reporting a case of an isolated DCRV in an asymptomatic young female patient.
