在解剖学和病理学文献中，有无数对人类心脏先天畸形的描述。其他哺乳动物也出现类似的异常现象，虽然推测也同样频繁，但记录的频率却要低得多。 Shaner（47 岁）最近报告说，在检查 15,000 个猪胚胎的心脏是否存在外部可见的异常时，他发现 33 个明显异常。因此，他有理由相信，猪的心脏异常发生的平均频率高于每 430 例中 1 例。Olafson ('39) 在“约 4,500 例”各种兽医尸检过程中，统计出 15 例产后“先天性心脏异常”，但其中 3 例是狗的右主动脉弓。将它们扣除为动脉病例而不是心脏病例，他的平均病例数为 450 分之一。考虑到它们的丰富性，Lilleengen ('34) 只能收集文献中描述的 129 个病例，他自己又添加了 37 个病例。这些，连同奥拉夫森的 10 份，总共 176 份，分布如下：牛 97 份，动物 29 份。尽管 Wimsatt 博士在 Harwrrl 医学院解剖学系工作期间完成了本报告的基本工作，但在他成为康奈尔大学动物学系成员后，对手稿进行了彻底的修订。牦牛心脏属于哈佛医学院所有，现已存放在康奈尔大学苏约克州立 Veteiinarp 学院病理学博物馆中。
In the literature of anatomy and pathology there are countless descriptions of congenital malformations of the human heart. Similar abnormalities in other mammals, though presuniably quite as frequent, have been recorded far less often. Shaner (’47) has recently reported that on examining the hearts of 15,000 pig embryos for externally visible anomalies, he found 33 which were distinctly abnomial. Thus he has reason to believe that anomalous hearts in the pig occur in greater average frequency than 1 in 430. Olafson (’39), in the course of “some 4.500” miscellaneous veterinary autopsies, counted 15 post-partuni “congenital cardiac anomalies,” but 3 of these were right aortic arches in dogs. Deducting them as arterial rather than cardiac, his average heconies 1 in 450. Xotwitlistancling their abundance, Lilleengen (’34) was able to assemble only 129 cases described in the literature, to which he added 37 of his own. These, with Olafson’s 10,- 176 altogether-were distributed as follows: 97 in cattle, 29 in theAlthongh the essential work for this report was completed while Dr. Wimsatt was a member of the Anatomy Department at the Harwrrl Medical School, a subseqiieiit thorough revision of the manuscript\\as made after he became a member of the Department of Zoology at Cornell TTniversity. Thr yak heart, which is the property of the IHarvard Medical School, has been deposited in the museum of pathology of the Sew York State Veteiinarp College at Cornell University.
