title: [Valvular lesions in the course of nonpenetrating thoracic trauma: their diagnosis by transesophageal echocardiography].
abstract: Two cases are reported with nonpenetrating chest trauma and involvement of mitral valve in one case and aortic valve cusps in the other, without aortic rupture. In both patients transesophageal echocardiography allowed us an accurate diagnosis, confirmed by surgical findings. In the patient with involvement of the aortic cusps, the regurgitation developed 3 months after the trauma. In conclusion, cardiac valve injuries are rare but not exceptional following nonpenetrating blunt chest trauma. Transesophageal echocardiography is the imaging technique of choice for these patients. The operator performing the study must be aware of the possible coexistence of different cardiac lesions secondary to blunt chest trauma. In the case of valvular regurgitation the accurate definition of the pathophysiological mechanism is mandatory in order to choose the appropriate surgical strategy. In the case of aortic incompetence of unknown origin, a nonpenetrating chest trauma must be searched out during the clinical interview.
