Abstract
One hundred and twenty-six Medotronic Hall(MH) valves were implanted in 117 patients between October 1982 and January 1990. MH valves were implanted in 102 patients for initial valve replacement, and in the 15 for redo replacement. In the 102 initial group, early mortality was 9.8% and late was 3.9%. Redo replacement was done in 5 patients due to prosthetic valve endocarditis, thrombosed valve, open stuck, and closed stuck. In the 15 redo group, early mortality was 40%. Thromboembolic episode was occurred in 4 patients; cerebrovascular arteries were involved in all and only one had persisted disturbance of visual field. According questionaries, 62.5% of patients with MH valves expressed their satisfaction with the results. Patients with MH valves showed relatively good postoperative results and almost similar results of patients with St. Jude Medical valves.
