Implication

Low early mortality and hemodynamic gains with Björk-Shiley AVR support further evaluation; leaves open long-term durability in prospective cohorts.

Structured PICO

Does aortic valve replacement with the Björk-Shiley tilting disc prosthesis improve clinical and hemodynamic outcomes in patients with aortic valve disease?

P
Population
101 patients with aortic valve disease (aortic stenosis n=29, aortic insufficiency n=29, combined lesions n=43)
I
Intervention
Aortic valve replacement with the Björk-Shiley tilting disc prosthesis
O
Outcome
Early and late mortality, clinical improvement, and hemodynamic changes (pressures, gradients, regurgitation)

Aortic valve replacement with the Björk-Shiley tilting disc prosthesis provides good clinical improvement and favorable hemodynamics with low obstruction to flow and no thrombo-embolic complications at 6-8 months.
