Abstract
A total of 675 patients (mean age 60±11 years, range 22–85, 71% males) with calcified pure aortic stenosis (490) or mixed lesions (185) had an aortic prosthesis: 290 Starr-Edwards, 147 Bjork, 18 other mechanical valves, 163 pericardial xenografts, 57 porcine xenografts; 76 patients simultaneously underwent a coronary bypass, 12 a replacement of ascending aorta, and six a mitral valvuloplasty. Preoperatively, 67% were in functional class III or IV (NYHA); 69·5% had a coronary arteriography: significant coronary stenosis was observed in 27% of patients.
