Merged bilateral arterial duct and circumflex retroesophageal right aortic arch in a fetus with normal intracardiac anatomy

Cardiol Young. 2019 Dec;29(12):1546-1548. doi: 10.1017/S1047951119002488. Epub 2019 Nov 4.

Abstract

We report the case of a fetus with anamnios sequence and VACTERL syndrome, having a circumflex right aortic arch. Two arterial ducts join anteriorly to form a common vessel that connects to the pulmonary trunk with confluent pulmonary branches. Embryologically, the dorsal right 6th aortic arch did not disappear and the aortic arch development stopped in a symmetrical state with an exceptional "Y-shaped" merged bilateral arterial duct.

Keywords: Bilateral arterial duct; VACTERL; circumflex aortic arch; right aortic arch.
