Penetrating injury to cardiac valves occurred in two patients. A patient with acute tricuspid insufficiency and conduction-bundle injury due to a gunshot wound had immediate valve replacement, pacemaker implantation, and excision of the lower lobe of the right lung with subsequent recovery. We believe this to be the first case of valve replacement for a gunshot wound successfully done at initial exploration. A patient had mitral insufficiency due to stab wound with eventual valve replacement. Early, definitive surgery with a heart-lung machine available is urged for all gunshot wounds and stab wounds suspected of causing major intracardiac damage.
