A primiparous woman with no family history of congenital heart disease was referred for fetal echocardiography at 22 weeks of gestation because of a shift in the cardiac axis from the normal plane. Initial fetal echocardiography demonstrated significant aortic regurgitation with a dilated left ventricle (LV). Repeat imaging at 26 weeks of gestation raised the possibility of an aortico-left ventricular tunnel. There was a large channel passing from the ascending aorta to the LV behind the right coronary cusp (Fig. 1). An eccentric jet of aortic regurgitation was noted on color Doppler. The LV remained dilated with normal function.
