An infant, who was conjoined to a partially formed twin, died from congenital cardiac disease which could not be diagnosed accurately by catheterization and cineangiography. Pathologic examination showed a triventricular heart with three atrioventricular valves. One great vessel system was present, and the aorta was transposed. The findings in this infant suggest that the incorporation of cardiac anlage from an incompletely or abortively formed fetus may explain the presence of supernumerary structures in complex congenital cardiac malformations.
一名与部分形成的双胞胎联体的婴儿死于先天性心脏病，这种疾病无法通过心导管检查和心血管造影准确诊断。病理检查显示为一个具有三个房室瓣的三心室心脏。存在一个大血管系统，且主动脉转位。该婴儿的这些发现表明，来自不完全或夭折胎儿的心脏原基融合可能解释了复杂先天性心脏畸形中多余结构的存在。
