Two Cases of Double-Chambered Right Ventricle without Other Congenital Cardiac Anomalies

ABSTRACT

Double-chambered right ventricle (DCRV) is a congenital cardiac anomaly in which the right ventricle is divided into two chambers by anomalous hypertrophied muscle bundles that cross the right ventricular cavity. DCRV may be associated with other congenital cardiac anomalies, most commonly with ventricular septal defect. We report two cases of DCRV without other congenital cardiac anomalies with review of literatures. We performed echocardiography, cardiac catheterization and right ventricular angiogram to confirm the diagnosis.
