Late presentation of retained intracardiac ice pick with papillary muscle injury.

An unusual case of a penetrating intracardiac injury is described in a 16-year-old boy who presented with a retained 14-cm segment of an ice pick that went unnoticed by the patient for 4 days. The ice pick had lacerated the anterior papillary muscle of the left ventricle causing avulsion of its tip and prolapse of the anterior leaflet of the mitral valve resulting in severe mitral regurgitation. The urgency for surgical correction of the traumatic mitral valve injury at the time of extraction of the intracardiac foreign body through a single-stage approach versus a two-stage approach is discussed.
