Survival after heart and coronary-artery penetration by an air-rifle projectile.
Gunshot injuries of the heart are extremely rare thoracic traumas in Europe during peacetime. Concomitant lesions of the coronary arteries occur in less than 5%. This case reports on a 26-year-old man who was shot with an air rifle at short range. On admission the patient showed signs of pericardial tamponade. Emergency thoracotomy was performed and a frontal cardiac lesion was found in the distal third of the anterior descending branch of the left coronary artery. The bullet crossed the cavum of the left ventricle and remained in the posterior wall in the subepicardial layer adjacent to the posterior descending coronary branch. Under the conditions of extracorporeal circulation we removed the bullet, repaired both ventricle walls using patches in sandwich technique, and bypassed the coronary lesion by single aortocoronary venous graft. No signs of myocardial infarction could be detected by ECG. The follow-up after 3 years shows no cardiac problems and normal stress tolerance. This case report proves that even air rifle shots, which in general are considered to be harmless, may result in life-threatening injuries. For the severity of the injury are decisive the kinetic energy at the muzzle as well as configuration and type of the bullet.
