Double Chambered Right Ventricle (DCRV)

Double chambered right ventricle (DCRV) is a form of congenital heart disease in which the right ventricle is divided by anomalous muscle bundles into two chambers which causes subpulmonary stenosis in the region of the right ventricle and right ventricular outflow tract. Obstruction may occur adjacent to the pulmonary valve or close to the RV apex. It may also develop over time as may be the case in a subset of patients who have a shortened distance between their RV moderator band and pulmonary valve.  Patients with VSDs are at a heightened risk of developing a (DCRV).
