Key result
Balloon aortic valvuloplasty demonstrates ~38% survival at 27 months in severe AS with cardiogenic shock.
Why the study?
Patients with cardiogenic shock and severe aortic stenosis have a poor prognosis and multiorgan failure often precludes surgery, making percutaneous aortic balloon valvuloplasty a potential alternative option.
Does percutaneous aortic balloon valvuloplasty improve hemodynamics and survival in patients with cardiogenic shock and critical aortic stenosis?
Population
21 patients in cardiogenic shock due to severe aortic stenosis with major comorbid conditions
Comparison

Design
Observational cohort study
Follow-up
15 +/- 6 months

May support valvuloplasty as bridge in select shock patients with severe AS; leaves open survival predictors pending prospective data.

Does percutaneous aortic balloon valvuloplasty improve hemodynamics and survival in patients with cardiogenic shock and critical aortic stenosis?
Emergency percutaneous aortic balloon valvuloplasty can serve as a lifesaving procedure and therapeutic alternative for nonsurgical patients with critical aortic stenosis and cardiogenic shock, despite high residual mortality.
Moreno et al. (1994) conducted an observational in Cardiogenic shock due to severe aortic stenosis (n=21). Percutaneous aortic balloon valvuloplasty was evaluated on Kaplan-Meier survival rate at 27 months. Percutaneous aortic balloon valvuloplasty in patients with cardiogenic shock and severe aortic stenosis resulted in a 57% in-hospital survival and a 38% Kaplan-Meier survival rate at 27 months.
