Prenatally diagnosed congenital right atrial aneurysm using three/four-dimensional spatiotemporal image correlation fetal echocardiography.

Right atrial aneurysm (RAA) is a rare congenital heart malformation that can originate from the free wall of the atrium or the appendage. We report a case of prenatally diagnosed RAA imaged using three-dimensional/four-dimensional spatiotemporal image correlation fetal echocardiography and its postnatal follow-up.
