There were also hearts in which the interventricular septum was deficient, the ductus arteriosus patent, or some valvular malformation present.

All these persons had reached puberty.
Displacements of the heart are quite numerous.

Deschamps of Laval made an autopsy on an old soldier which justified the expression, "He had a heart in his belly." This organ was found in the left lumbar region; it had, with its vessels, traversed an anomalous opening in the diaphragm.
Franck observed in the Hospital of Colmar a woman with the heart in the epigastric region.

Ramel and Vetter speak of the heart under the diaphragm.
Inversion of the heart is quite frequent, and we often find reports of cases of this anomaly.

Fournier describes a soldier of thirty years, of middle height, well proportioned and healthy, who was killed in a duel by receiving a wound in the abdomen; postmortem, the heart was found in the position of the right lung; the two lungs were joined and occupied the left chest.
The anomalies of the vascular system are so numerous that we shall dismiss them with a slight mention.
