Conservative management of retained cardiac missiles: case report and literature review.
Intracardiac foreign bodies may be caused by direct penetrating trauma, embolization from injury to another area of the body, or iatrogenically from fragments of intravascular access devices. Penetrating cardiac trauma commonly presents with a hemodynamically unstable patient necessitating emergent life-saving procedures. Missile embolization to the heart can occur after injury to systemic and pulmonary veins. Central venous access devices may fracture after placement and embolize. Especially in the setting of penetrating cardiac trauma, these intracardiac foreign bodies require expeditious removal. Limited data exist regarding the conservative management of intracardiac material after trauma. We present the case of a 42-year-old male soldier injured in a mortar blast in Iraq who suffered multiple injuries to include a right hemopneumothorax and soft tissue injuries to the chest and both lower extremities that was found to have a 2-cm by 2-mm intracardiac metal fragment. Additional imaging revealed a metallic fragment localized to the interatrial septum. The patient suffered no adverse sequelae from nonoperative management. A review of the world literature regarding the subject of posttraumatic retained cardiac missiles (RCMs) is also included to help future surgeons in the management of this rare entity.
