Implication
Provides acute hemodynamic benefit in severe aortic stenosis with low ejection fraction; leaves open long-term outcomes and modern role.
Structured PICO
Does percutaneous balloon aortic valvuloplasty improve hemodynamics and clinical outcomes in patients with severe aortic stenosis and low ejection fraction?
P
Population
55 consecutive patients with severe aortic stenosis and low ejection fraction (<40%), mean age 77 years. 45 patients were definitely not surgical candidates due to age, poor left ventricular function, and associated diseases.
I
Intervention
Percutaneous balloon aortic valvuloplasty using 15-23-mm diameter balloon catheters
O
Outcome
Immediate hemodynamic changes (transvalvular gradient, valve area, ejection fraction) and clinical follow-up (mortality, clinical improvement)
Balloon aortic valvuloplasty provides immediate hemodynamic and clinical improvement in high-risk patients with severe aortic stenosis and low ejection fraction, though long-term mortality and restenosis rates remain high.
