Heart valve replacement with the new all-pyrolytic bi-leaflet St. Jude medical prosthesis

Since February 1978, seventy-nine St. Jude medical prostheses have been implanted in seventy-two patients with an overall mortality of 8.5%. Clinical, hemodynamic and hematological findings are presented. Twenty-two patients have been catheterized postoperatively, and findings are presented. In vitro comparisons have made between the St. Jude and other prostheses.
