title: Entrapment of leaflet of St. Jude medical cardiac valve prosthesis by miniscule thrombus: report of two cases.
abstract: Two patients with dysfunction of the St. Jude Medical cardiac valve prosthesis, one in the aortic and one in the mitral position, are presented. In both, one of the valve leaflets was jammed by a very small thrombus that fixed the leaflet in a semiclosed position. Neither patient received anticoagulation postoperatively. Because of the pathological findings in these 2 patients, anticoagulation for patients with a St. Jude Medical valve prosthesis is recommended for life.
