Abstract

The double-chambered right ventricle is congenital or acquired cardiac anomaly, which is characterized by aberrent hypertrophied muscular bands that divide the right ventriclar cavity into two different pressure chamber. This anomaly can complicate the natural history of patient with isolated ventricular septal defect. We experienced two cases of acquired DCRV, which confirmed by two separate cardiac catherterization and angiography. The purpose of this report is to show that the aberrant muscular bands may be nonobstructive in early infancy and that the obstructive effect is developed with time as the bands become progressively more hypertrohied.
