We report 4 cases of valvular injury following nonpenetrating cardiac trauma in 3 men and 1 woman ranging in age from 24 to 72 years. In all cases the cause of trauma was blunt chest trauma. One patient was operated in 4 h, but the other 3 patients were operated on more than 6 months after the accidents. Lacerated aortic cusp was observed in 2 patients, ruptured anterior papillary muscle of mitral valve, and ruptured chordae tendinae of the tricuspid vale were observed in 1 patient each respectively. Three patients underwent valve replacementi2 aortic and 1 mitral valves), and another patient underwent chordoplasty in the tricuspid valve. Their post-operative courses were uneventful. Careful observation, such as echocardiography, were required following the blunt chest trauma.
