Mobile intrapericardial bullet.

Patients with bullets in the pericardial sac without myocardial injuries are rare, and most commonly are associated with significant trauma. The diagnosis of an intrapericardial foreign body can be difficult. Its removal is always indicated because it prevents pericarditis, either sterile or infectious, with potential for other significant complications. The authors present two cases of a meandering bullet in the pericardial sac and propose approach and perform review of the literature.
