Abstract |
Cor triatrium dexter is a rare congenital anomaly, in which persistent Rt. side valve of sinus
venosus subdivides the Rt. atrium into two chambers. Although this lesion was described earlier by
Rokitansky, et al, the term “Cor triatrium dexter” was coined by German pathologists in the
beginning of this century. The most cases of the Cor triatrium dexter are due to persistence of fetal
Eustachian & Thebesian valves which form a septum across the lower part of the right atrium. Most
of the patients with this anomaly are usually asymptomatic unless associated with other congenital
cardiac anomaly. Therefore it may not be possible to find a clinical account of isolated Cor triatrium dexter.
We have experienced a 22 months-old girl who had an excessive membranous septum in the right
atrium associated with a severe valvular pulmonary stenosis and a right to left shunt at the atrial
level. A brief review of related literatures is given.
