Cor Triatriatum Dexter (CTD), is a very rare congenital anomaly in which right atrium is partitioned to form three chambered heart. It is caused by the persistence of the right valve of the sinus venosus. We herein report a case, where during routine dissection on the heart of male cadaver, a well-developed membrane was seen, separating the smooth and rough parts of right atrium. This can have varying clinical manifestations depending on the degree of partition of the right atrium. Knowledge about presence of such membrane is important for physician’s, as severe partition can lead to obstruction of the tricuspid valve, the right ventricular outflow tract, or the inferior vena cava associated with right-sided heart failure and elevated central venous pressures.
