A macroscopic description of four hearts showing three arterial ostia in the base of the pig's heart was carried out. Portions of the vascular walls were histologically examined in three hearts. All hearts belong to the Tetralogy of Fallot group. Spitzer's hypothesis concerning the phylogenetic development of the mammalian heart was tested against the observations. The hypothesis could not be verified. The study leads to the conclusion that the ductus arteriosus has its origin in the base of the heart in the four hearts studied.
对四颗猪心进行了宏观描述，这些猪心在心底显示出三个动脉口。对三颗猪心的血管壁部分进行了组织学检查。所有心脏都属于法洛四联症组。根据观察结果检验了斯皮策关于哺乳动物心脏系统发育的假说。该假说无法得到证实。研究得出结论，在所研究的四颗心脏中，动脉导管起源于心脏底部。
