title: Double-Chambered Right Ventricle with Ventricular Septal Defect and Subaortic Membrane- Three-Dimensional Echocardiographic Evaluation.
abstract: Double-chambered right ventricle (DCRV) is a rare congenital anomaly in which the right ventricle is divided into two compartments with varying pressures due to an anomalous muscle bundle. Here, we describe a case of an adolescent male with DCRV with associated ventricular septal defect and subaortic membrane. Two-dimensional and three-dimensional transthoracic echocardiography with color flow clearly outlined all the three cardiac anomalies as well as their relationship with each other. The diagnosis was confirmed by cardiac catheterization. The patient underwent successful surgical resection of the anomalous muscle bundle along with repair of the associated anomalies.
