Early and 8 year results of aortic valve replacement: a clinical study of 232 patients.

The study concerns early and late results of aortic valve replacement (AVR) in 232 patients with aortic valve disease, using the Björk-Shiley tilting-disc prosthesis. Of the 232, 27 patients had some evidence of mitral valve disease with valvulotomy having been undertaken in 7 previously, and in 12 at the time of the aortic valve replacement. Patients who underwent simultaneous mitral valve replacement and/or aorta coronary artery bypass grafting are not included in this analysis.
