Özet
Double-chambered right ventricle (DCRV) is defined as the progressive division of the right ventricle into two chambers: a high-pressure inlet chamber and a low-pressure outlet chamber. To date, only three cases diagnosed prenatally have been reported in the literature, all of which were associated with unfavorable pregnancy outcomes. In this study, we discuss DCRV in general, along with two cases of type 1 DCRV that did not cause hemodynamically significant obstruction and resulted in successful pregnancy outcomes. From a hemodynamic perspective, the following echocardiographic criteria may affect the prenatal fetal process: (1) detection of tricuspid regurgitation on echocardiography; and (2) pulmonary blood flow velocity and the difference in pressure between the proximal and distal right ventricle.
