Tricuspid valvular incompetence and rupture of the ventricular septum caused by nonpenetrating trauma.

A young adult involved in an automobile accident had tricuspid valvular incompetence and rupture of the ventricular septum owing to blunt trauma. He had a successful repair of the ventricular septal defect and replacement of the tricuspid valve. Tricuspid valvular incompetence owing to nonpenetrating trauma is uncommon. Blunt trauma resulting in rupture of the ventricular septum is rare. Rupture of the membranous portion of the ventricular spetum is extremely rare. This is the first report of a patient having a combination of these lesions.
