Clinical Evaluation of the Omniscience Aortic Disc Valve Prosthesis

Structured PICO

What are the clinical and hemodynamic outcomes of aortic valve replacement using the Omniscience valve?

Population

100 cases of aortic valve replacement

Intervention

Omniscience aortic disc valve prosthesis

Outcome

Clinical results and hemodynamics (late survival rate, clinical improvement, and cardiac and prosthetic valve performance)composite

The Omniscience aortic disc valve prosthesis showed satisfactory early clinical performance, though thromboembolism occurred at 4.7%/patient year and incomplete disc opening was observed in 18% of cases.

Abstract

The clinical results and hemodynamics were evaluated in 100 cases of aortic valve replacement, using the Omniscience valve, in the period December 1980 through 1984. Late survival rate, clinical improvement and cardiac and prosthetic valve performance were acceptably satisfactory. The overall incidence of thromboembolism was 4.7%/patient year. The opening angle of the disc was less than 60 degrees in 18% of the studied cases. Further investigations are required to determine if such results were related to the valve structure or to some cause in the recipient. Assessment of the durability of the Ominiscience cardiac valve prosthesis must await the results of long-term observation.
