A hitherto undescribed cardiac malformation, characterized by persistence of the primitive aortic conus and normal positioning of the great vessels, is reported and used to discuss the theory of bulbar resorption and the hypothesis of conal growth. The persistence of the primitive aortic conus is explained by the absence of bulbar contraction. The present selective inhibition of bulbar involution in normal positioning of the great vessels shows it to be a phenomenon formally independent of the transposition. Thus, the concept explaining the formal genesis of transposition is explained by arrest of torsion of the bulbar truncus is reconfirmed.
报道了一种迄今未被描述的心脏畸形，其特征为原始主动脉圆锥持续存在且大血管位置正常，并以此来讨论球部吸收理论和圆锥生长假说。原始主动脉圆锥的持续存在是由于球部收缩缺失所致。目前在大血管正常位置时球部退化的选择性抑制表明这是一种形式上独立于转位的现象。因此，解释转位形式发生的概念，即球部动脉干扭转停止，再次得到证实。
