Wounds of the heart are not necessarily fatal. Of 401 cases of cardiac injury collected by Fischer there were as many as 50 recoveries, the diagnosis being confirmed in 33 instances by an autopsy in which there were found distinct signs of the cardiac injury. By a peculiar arrangement of the fibers of the heart, a wound transverse to one layer of fibers is in the direction of another layer, and to a certain extent, therefore, valvular in function; it is probably from this fact that punctured wounds of the heart are often attended with little or no bleeding.

Among the older writers, several instances of nonfatal injuries to the heart are recorded. Before the present century scientists had observed game-animals that had been wounded in the heart in the course of their lives, and after their ultimate death such direct evidence as the presence of a bullet or an arrow in their hearts was found. Rodericus a Veiga tells the story of a deer that was killed in hunting, and in whose heart was fixed a piece of arrow that appeared to have been there some time. Glandorp experimentally produced a nonfatal wound in the heart of a rabbit. Wounds of the heart, not lethal, have been reported by Benivenius, Marcellus Donatus, Schott, Stalpart van der Wiel, and Wolff. Ollenrot reports an additional instance of recovery from heart-injury, but in his case the wound was only superficial.

There is a recent case of a boy of fourteen, who was wounded in the heart by a pen-knife stab. The boy was discharged cured from the Middlesex Hospital, but three months after the reception of the injury he was taken ill and died. A postmortem examination showed that the right ventricle had been penetrated in a slanting direction; the cause of death was apoplexy, produced by the weakening and thinning of the heart's walls, the effect of the wound. Tillaux reports the case of a man of sixty-five, the victim of general paralysis, who passed into his chest a blade 16 cm. long and 2 mm. broad. The wound of puncture was 5 cm. below the nipple and 2 cm. to the outside. The left side of the chest was emphysematous and ecchymosed. The heart-sounds were regular, and the elevation of the skin by the blade coincided with the ventricular systole. The blade was removed on the following day, and the patient gradually improved. Some thirteen months after he had expectoration of blood and pus and soon died. At the necropsy it was seen that the wound had involved both lungs; the posterior wall of the ventricle and the inferior lobe of the right lung were traversed from before backward, and from left to right, but the ventricular cavity was not penetrated. Strange to say, the blade had passed between the vertebral column and the esophagus, and to the right of the aorta, but had wounded neither of these organs.

O'Connor mentions a graduate of a British University who, with suicidal intent, transfixed his heart with a darning-needle. It was extracted by a pair of watchmaker's pliers. In five days the symptoms had all abated, and the would-be suicide was well enough to start for the Continent. Muhlig was consulted by a mason who, ten years before, had received a blow from a stiletto near the left side of the sternum. The cicatrix was plainly visible, but the man said he had been able to perform his daily labors, although at the present time suffering from intense dyspnea and anasarca. A loud bellows-sound could be heard, which the man said had been audible since the time of reception of the injury. This was a double bruit accompanying systole, and entirely obscuring the physical signs. From this time the man speedily failed, and after his death there were cicatricial signs found, particularly on the wall of the left ventricle, together with patency of the interventricular septum, with signs of cicatrization about this rent. At the side of the left ventricle the rent was twice as large and lined with cicutricial tissue.

Stelzner mentions a young student who attempted suicide by thrusting a darning-needle into his heart. He complained of pain and dyspnea; in twenty-four hours his symptoms increased to such an extent that operation was deemed advisable on account of collapse. The 5th rib was resected and the pleural cavity opened. When the pericardial sac was incised, a teaspoonful of turbid fluid oozed out, and the needle was felt in an oblique position in the right ventricle. By pressure of a finger passed under the heart, the eye of the needle was pressed through the anterior wall and fixed on the operator's finger-nail. An attempt to remove by the forceps failed, as the violent movements of the heart drew the needle back into the cavity. About this stage of the operation an unfortunate accident happened - the iodoform tampon, which protected the exposed pleural cavity, was drawn into this cavity during a deep inspiration, and could not be found. Notwithstanding subsequent pneumothorax and extensive pleuritic effusion, the patient made a good recovery at the end of the fourth week and at the time of report it was still uncertain whether the needle remained in the heart or had wandered into the mediastinum. During the discussion which followed the report of this case, Hahn showed a portion of a knitting-needle which had been removed from the heart of a girl during life. The extraction was very slow in order to allow of coagulation along the course of the wound in the heart, and to guard against hemorrhage into the pericardial sac, which is so often the cause of death in punctured wounds of this organ. Hahn remarked that the pulse, which before the removal had been very rapid, sank to 90.

Marks reports the case of a stab-wound penetrating the left 9th intercostal space, the diaphragm, pleura, pericardium, and apex of the heart. It was necessary to enlarge the wound, and, under an anesthetic, after removing one and one-half inches of the 9th and 10th ribs, the wound was thoroughly packed with iodoform gauze and in twenty-one days the patient recovered. Lavender mentions an incised wound of the heart penetrating the right ventricle, from which the patient recovered. Purple gives, an account of a recovery from a wound penetrating both ventricles. The diagnosis was confirmed by a necropsy nine years thereafter. Stoll records a nonfatal injury to the heart.

Mastin reports the case of a man of thirty-two who was shot by a 38-caliber Winchester, from an ambush, at a distance of 110 yards. The ball entered near the chest posteriorly on the left side just below and to the outer angle of the scapula, passed between the 7th and 8th ribs, and made its exit from the intercostal space of the 4th and 5th ribs, 2 1/4 inches from the nipple. A line drawn from the wound of entrance to that of exit would pass exactly through the right ventricle. After receiving the wound the man walked about twenty steps, and then, feeling very weak from profuse hemorrhage from the front of the wound, he sat down. With little or no treatment the wound closed and steady improvement set in; the patient was discharged in three weeks. As the man was still living at last reports, the exact amount of damage done in the track of the bullet is not known, although Mastin's supposition is that the heart was penetrated.

Mellichamp speaks of a gunshot wound of the heart with recovery, and Ford records an instance in which a wound of the heart by a buckshot was followed by recovery. O'Connor reports a case under his observation in which a pistol-ball passed through three of the four cavities of the heart and lodged in the root of the right lung. The patient, a boy of fifteen, died of the effects of cardiac disease three years and two months later. Bell mentions a case in which, six years after the receipt of a gunshot wound of the chest, a ball was found in the right ventricle. Christison speaks of an instance in which a bullet was found in the heart of a soldier in Bermuda, with no apparent signs of an opening to account for its entrance. There is a case on record of a boy of fourteen who was shot in the right shoulder, the bullet entering through the right upper border of the trapezius, two inches from the acromion process. Those who examined him supposed the ball was lodged near the sternal end of the clavicle, four or five inches from where it entered. In about six weeks the boy was at his labors. Five years later he was attacked with severe pneumonia and then first noticed tumultuous action of the heart which continued to increase after his recovery. Afterward the pulsation could be heard ten or 12 feet away. He died of another attack of pneumonia fifteen years later and the heart was found to be two or three times its natural size, soft and flabby, and, on opening the right ventricle, a bullet was discovered embedded in its walls. There was no scar of entrance discernible, though the pericardium was adherent. Biffi of Milan describes the case of a lunatic who died in consequence of gangrene of the tongue from a bite in a paroxysm of mania. At the necropsy a needle, six cm. in length, was found transfixing the heart, with which the relatives of the deceased said he had stabbed himself twenty-two months prior to his death. There is a collection of cases in which bullets have been lodged in the heart from twenty to thirty years.
