Isolated mitral valve injury from non-penetrating cardiac trauma. Report of a case with successful repair.

Isolated mitral valve injury from non-penetrating cardiac trauma was low in incidence. A successfully operated case of a patient with acute mitral insufficiency from non-penetrating cardiac injury due to a traffic accident was reported and discussed. This isolated mitral valve lesion, of which the posterior leaflet was torn away from the annulus with intact chordae tendineae and papillary muscle, was very rare in the literature. And, particularly, the preoperative non-invasive findings such as echocardiogram and ACG were mostly useful and important in our case. This case was the fourth successful repaired case on blunt isolated mitral valve injury in the literature.
