Implication

May support small Björk-Shiley valves in narrow aortic roots; leaves open need for randomized comparisons.

Structured PICO

Does the 21 mm Björk-Shiley tilting disc valve improve clinical and haemodynamic outcomes in patients with aortic valvular lesions and narrow aortic roots?

P
Population
23 consecutive patients with aortic valvular lesions and narrow aortic roots (19 subjected to detailed pre- and postoperative study)
I
Intervention
Aortic valve replacement with the 21 mm Björk-Shiley tilting disc valve prosthesis
O
Outcome
Clinical and haemodynamic changes (including left ventricular systolic pressure, stroke work, and pressure gradients)surrogate

The 21 mm Björk-Shiley tilting disc valve provides satisfactory haemodynamic unloading of the left ventricle and clinical improvement in patients with narrow aortic roots.
