title: Thromboembolic phenomena in patients with prosthetic aortic valves who did not receive anticoagulants.
abstract: Seventy-two patients with Starr-Edwards aortic prostheses of the 2300 series were followed for 1 to 73 months (average, 22 months) without receiving anticoagulants. Nine patients had clinical evidence of an embolic episode (12.5%). One of these patients died, and 5 were left with a significant residual neurological deficit. Two other patients had hemiparesis but recovered fully. Only 1 episode could be considered minor. The reported lower incidence of thromboembolism in patients receiving this prosthesis with adequate anticoagulation has now led us to reverse our previous position and recommend anticoagulation for patients receiving Starr-Edwards aortic prostheses.
