Experience with 105 patients in whom the Magovern aortic valve prosthesis was employed and who were followed for up to five years is presented and analyzed. Twenty-eight patients had a second valve repaired or replaced, four had triple valve disease, and four had aneurysms of the ascending aorta in addition to the aortic valve disease. The ages of these patients ranged from 21 to 74 years with 23 patients in the seventh and eighth decades of life. There were eight operative deaths (8%) and 17 late deaths (17%). Four late deaths were due to embolization or bleeding. Seventeen patients (16%) suffered emboli, and eight (8%) had significant bleeding complications for a total of 25 complications from these causes. Permanent heart block occurred in 9% of the patients and was as common late after operation as early. Although two patients required reoperation because of leaks, in no instance did the prosthesis work loose if it was properly sized and properly positioned.
