Penetrating cardiac injury by wire thrown from a lawn mower.

The first successful surgically treated case of penetrating heart injury, specifically the right ventricle, caused by a fragment of coat hanger wire thrown by a lawn mower, is reported. Though traumatic heart injuries are rare, this case represents accurate surgical management and judgment, especially in the preoperative phase which resulted in early operating and excellent postoperative results. It is our feeling that if the patient can be transferred safely to the operating room the mortality rate is considerably lowered; however, emergency room thoracotomy, which will undoubtedly result in a greater survival rate from these spectacular injuries, should be performed in the emergency center if cardiac activity ceases or the patient's condition deteriorates considerably.
