RESUMO
Structural failure of a Model 2400 Starr-Edwards aortic track valve occurred suddenly, 4 years after implantation. At operation, the valve cage was removed from the descending aorta. Examination of the excised prosthesis disclosed minimal cloth wear and no evidence of infective growth; however, three struts were fractured above their insertion into the valve ring. To our knowledge, this type of valve malfunction has not been previously noted.
