Rupture of mitral chorda tendinea following blunt chest trauma

Acute mitral insufficiency, originated from rupture of mitral chordae tendineae secondary to nonpenetrating thoracic trauma, is an unusual condition. This diagnosis is difficult to establish because physical examination, electrocardiogram, and cardiac enzymes are neither sensitive nor specific. The diagnosis of rupture must be quickly established because this disorder may be fatal. This paper reports the case of a patient with acute mitral insufficiency secondary to a mitral valve chord rupture a week after a nonpenetrating thoracic trauma.
