Traumatic disruption of the aortic valve.

A insufficiency is a rare but well-defined consequence of nonpenetrating chest trauma. The injury may occur as an isolated incident, and occasionally is induced through straining or relatively minor degrees of concussion. Unlike disruption of the thoracic aorta, which is associated with a high, early mortality, the torn aortic valve frequently permits a longer period of survival. Effective treatment during this time interval was not forthcoming, however, until the advent of cardiopulmonary bypass and the development of valvular prostheses. During the past decade, traumatic aortic valve incompetence has received attention repeatedly, particularly after vehicular accidents. Our experience with a case of aortic leaflet injury is presented and compared with recent reports in the world literature.
