Abstract
Blunt cardiac injury is caused by large deceleration forces seen in motor vehicle accidents and can range from non-life-threatening arrhythmias to potentially fatal cardiac conditions such as valve disruption. A 28-year-old man presented following a motor vehicle accident involving direct blunt-force chest trauma. He developed papillary muscle rupture resulting in mitral valve dysfunction. Diagnosis was delayed due to concomitant chest pathology. Diagnosis of cardiac valvular injuries may be difficult due to concomitant injuries in a trauma patient. Though rare, papillary muscle rupture should be included in the differential diagnosis following blunt thoracic trauma, particularly involving persistent hypoxemia.
